In this work different receiver-side interference compensation techniques are studied in a spatially multiplexed fiber-optic transmission through 0.5 km multi-mode fiber with a gross bit-rate of 5 Gbps using intensity modulation and direct detection. Broadband successive interference cancellation (SIC) and broadband zero forcing (ZF) equalization are compared as electronic interference compensation methods in a (2×2) MIMO transmission. The results show that ordered SIC can significantly improve the transmission quality compared to the ZF equalization approach in the studied testbed configuration. Also, spatial filtering as an interference reduction technique is studied with respect to its effect on the bit-error rate (BER) performance, showing that in the analyzed channel scenario the use of such a filter is beneficial. Using a spatial filter improves the mode group separation at the receiver and hence reduces the MIMO signal processing complexity.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126903790","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}

MIMO-CEM has a transmitter system with an efficient non-linear power amplifier and a receiver system with a 1-bit Analog to Digital Converter (ADC) sampled at the Intermediate Frequency (IF). In spite of the great reduction in power consumption and hardware complexity as a result of using 1-bit ADC at the receiver side, a big degradation in the bit error rate performance (BER) is observed. This was a result of using 1-bit ADC which cause a severe quantization noise. Therefore, an efficient error correction coding becomes a major to solve this problem. In this paper, a comprehensive study for channel coding technique for MIMO-CEM system is done to select the most suitable channel coding technique to improve MIMO-CEM BER performance. The evaluation of this study was done over a multipath Rayleigh fading channel with both Minimum Shift Keying (MSK) modulation and Gaussian Minimum Shift Keying (GMSK) modulation. The simulation results show a significant improvement in the BER performance at low values of Signal to Noise Ratio (SNR) when LDPC channel coding is used while, the Convolutional Code (CC) with Viterbi Decoder achieves the best BER performance at high SNR values.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129528062","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}

Since higher data rates, lower latency and increased fairness for users are the main goals, an efficient scheduling algorithm has to be used. In this paper an evaluation of the performance of an indoor network is realised using the Realistic Indoor Environment Generator (RIEG), when 20 different Throughput Quantile Averaging Methods (TQAMs) for the downlink Resource Allocation Algorithm (RAA) called Proportional Fair (PF) are used. The TQAMs are compared by using a trustworthy metric called Comparative Factor (CF), which evaluates the overall performance of the mobile network, simultaneously taking into account the average throughput of the indoor users, the fairness of resource distribution and the outage ratio. Each type of the TQAMs takes a different part of the previous throughputs to evaluate the average throughput used by the PF scheduling algorithm in order to allocate network resources to the users. The experimental results show that the TQAMs which incorporate bigger groups of previous throughputs are more stable when the number of users increases. When the min-max groups are taken into account an increase of overall throughput is observed, while using the min or max groups leads to an increase in fairness. The performance of the cell-edge users is improved the most when the max or middle part of the previous throughputs is taken into account.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132072500","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}
