To accomplish this in a flexible and a cost-effective manner, priority classes for the different services are commonly used. The authors study priority queueing schemes implemented in a statistical multiplexer with shared and separate buffers, whose input consists of superposition of voice and data traffic. A performance comparison is given for two buffer access schemes: the common nested threshold cell discarding (NTCD) with single shared buffer and NTCD with multiple buffers (NTCD-MB). The arrival process to the multiplexer is approximated using a Markov modulated Poisson process (MMPP). It is shown that when implementing the NTCD-MB priority scheme, the parameters of the switching node can be adjusted in such away that the service quality is guaranteed for different classes of traffic. The improved performance as a result of implementing such scheme is investigated via simulations.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121875281","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}

In particular, the use of a satellite backbone communications link whose channels are dynamically assigned to the network stations is investigated. Each station supports packetized voice and data message streams. Incoming streams to a station are statistically multiplexed by the station across the backbone channels currently allocated to this station. To enhance the multiplexing process, a variable bit-rate packet-voice encoding scheme is also employed. Stations issue periodically requests for backbone channel allocations, based upon their loading status. We introduce two distinct algorithms for allocating the shared backbone channels to the stations. We develop analytical methods for the analysis and design of such integrated multiplexing/multiple-access networks. Performance measures include voice and data packet delays and packet blocking probabilities. Voice stream performance is also characterized by the average number of bits per sample used by the voice encoding scheme. The fairness issues between the two allocation algorithms are described and discussed. The effects of the propagation delay across the backbone link are especially demonstrated.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"43 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114041714","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}

Determination of the presence of such signals can be performed by radiometer-based intercept receivers that detect the signal's presence by measuring received power. However, conventional intercept receivers often fail when they operate in the presence of narrow-band interference because of their inability to differentiate between jammer and DSSS signal energy. An intercept receiver which employs wavelet transform domain-based excision is described. The receiver detects BPSK DSSS signals in the presence of narrow-band interference by employing adaptive interference rejection techniques to suppress the interference before measuring power. The improvement in the system performance over that of conventional radiometric detection only is shown by presenting numerical simulation results in the form of receiver operating characteristics. Performance is also compared to that for intercept receivers that use FFT-based excision systems techniques.<<ETX>>","PeriodicalId":112111,"journal":{"name":"Proceedings of ICC/SUPERCOMM'94 - 1994 International Conference on Communications","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115140887","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}
