In this talk, the steady state analyses of the residual SI powers in both analog and digital domains are derived in frequency domain. It is proved that the ALMS loop amplifies the frequency components of the residual SI at the edges of the signal spectrum in the analog domain, but the matched filter in the receiver chain reduces this effect. This results in a significant improvement of the interference suppression ratio in the digital domain before information data detection. The lower bounds of the interference suppression ratio given by the ALMS loop in both analog and digital domains are then addressed. These lower bounds are proved to be joint effects of the loop gain, tap delay, number of taps, and transmitted signal properties. The discovered relationship among these parameters allows the flexibility in choosing appropriate parameters when designing the IBFD systems under given constraints. Finally, the effects of I/Q imbalance in the ALMS loop and the upper bound of the degradation on SI cancellation performance are then investigated. The degradation is proved to be insignificant even under severe conditions of I/Q imbalance. The upper bound of the degradation provides an essential reference for the system design.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127028277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced human-machine interfaces (HMIs) and related head-mounted displays (HMDs) support different levels of computer-generated virtual worlds. These worlds include mobile virtual reality (VR), mobile augmented reality (VR), and mobile mixed reality (MR) which are jointly captured under the term mobile extended reality (XR). In addition, the development of fifth generation (5G) mobile networks aims at catering for ultra-reliable low-latency communications such as mobile XR and the tactile Internet. In this context, 5G mobile networks are essential enablers to carry mobile XR beyond video gaming to the general consumer and industry markets. In this keynote lecture, the fundamentals of interconnected immersive mobile multimedia are reviewed, and opportunities, challenges, and enablers are discussed. An overview of immersive mobile multimedia from mobile video to mobile 360-degree video, mobile VR, mobile AR, mobile MR, and mobile XR is provided. Major components of interconnected immersive mobile multimedia will be discussed and application opportunities in different vertical industries are pointed out. Furthermore, challenges associated with the delivery of immersive mobile XR applications are shown through service integrity parameters. Several enablers for interconnected immersive mobile multimedia applications are highlighted including standardization activities.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128608924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of the wireless internet of things with a massive machine-to-machine communications raised the importance of power consumption for sophisticated algorithms, such as channel equalization or decoding. The strong link existing between computational speed and power consumption suggests an investigation of signal processing with energy efficiency as a prominent design choice. Therefore we revisit the topic of signal processing with analog circuits and its potential to increase the energy efficiency. Channel equalization is chosen as one application of nonlinear signal processing, and a vector equalizer based on a recur-rent neural network (RNN) structure is taken as an example to demonstrate the potential of state of the art in very large scale integration (VLSI) design. We show for this example that it is possible to achieve an energy requirement of few pJ/bit, an improvement of three to four orders of magnitude compared with the most energy efficient digital circuits. As a second example, we consider iterative decoding algorithm based on message passing. They can be represented by a generalized RNN structure. Again, this allows to derive an equivalent analog circuit. Compared to digital circuits, analog circuits allow to perform iterative decoding or equalization with increased computational speed, reduced chip area and power consumption.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114700542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that packet contention is a critical issue for increasing the throughput in the uncoordinated transmissions. Thus, how to deal with packet contentions is the key for novel efficient multiple access schemes of future wireless communication networks. In this talk, we investigate the design and analysis of random multiple access schemes and coding techniques for the future machine to machine. We design the optimal coded slotted Aloha (CSA) scheme with repetition codes and maximum distance separable (MDS) codes under both packet erasure channels and slot erasure channels. We derive an upper bound on the throughput of CSA scheme. We show that our optimal distributions improve the maximum traffic load and enhance the throughput of the CSA scheme significantly. Moreover, we propose a Gaussian elimination (GE) aided successive interference cancelation (SIC) decoding (GE-SIC) method to further improve the throughput of the CSA scheme. We demonstrate that by introducing the GE decoding to recover packets that cannot be decoded by the SIC decoding, the peak throughput of CSA scheme can reach as high as 90%.","PeriodicalId":261348,"journal":{"name":"International Conference on Signal Processing and Communication Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114288265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
