It is assumed that the adaptive receiver and transmitter have no knowledge of the signature waveforms and timing of other users. The receiver and transmitter are trained by a known training sequence prior to data transmission and continuously adjusted by an adaptive algorithm during data transmission. The proposed linear structure is as simple as a standard single-user-detector receiver consisting of a matched filter with constant coefficients except that it requires separate channel for the transmitter adaptation. The concept of an adaptive transmitter maintains advantages with respect to timing recovery, near far effect, narrow-band and frequency selective fading interference suppression and user privacy compared to the systems with conventional matched filter receiver and further improves multiple-access interference elimination compared with the systems employing an adaptive receiver only. The proposed concept of adaptive transmitter and receiver are tested by simulation over a channel with multiple access interference and additive white Gaussian noise.<<ETX>>","PeriodicalId":158358,"journal":{"name":"Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129193212","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}

We analyze the performance of the down-link (i.e. the base-to-mobile link) of a low Earth orbiting (LEO) mobile satellite channel. An important characteristic of this fading channel is that the desired signal and the multiple access interference from the same base station fade simultaneously. As a consequence, the performance degradation due to fading will be smaller than for the mobile-to-base links, where fading of the desired signal and the interference are independent. In the limit, one can distinguish between two extreme scenarios. When the thermal noise is dominant relative to multiple access interference, the performance approaches that of a single user in fading channels. At the other extreme, when the energy-per-bit-to-noise power spectral density ratio is very high, the effect of fading on the desired signal becomes negligible, because the equivalent signal-to-noise ratio remains practically constant, in the absence of multiple access interference from other base stations. In practical situations, there may be multiple access interference from other satellites, and the ratio of energy-per-bit-to-thermal noise power spectral density has some finite valuer between the two extreme cases. We analyze the probability of error for the down-link of a mobile satellite channel when coherent detection, diversity and forward error correction are employed.<<ETX>>","PeriodicalId":158358,"journal":{"name":"Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94)","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114396126","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}
