The original Sirius system utilizes three satellites in highly inclined orbits. The original XM system utilizes two satellites in geostationary orbits. Both systems achieve a coverage pattern with high visibility to two satellites at all times. Robust diversity and signal coding techniques further ensure reliable reception of over one hundred audio channels, three video channels, and a range of data services. Recently Sirius XM added a new satellite to the Sirius fleet that operates in a geostationary orbit, and soon will be launching two new satellites to join the XM and Sirius fleets, both operating in geostationary orbits. This paper provides an overview of the Sirius and XM broadcast system designs and applications, and describes the coverage benefits achieved through the employment of geosynchronous and geostationary space segments in the North American continent. In addition to presenting the operational satellite radio conditions in the US, we will provide a discussion on offering similar services in the rest of the world with respect to possible satellite and repeater network structures with particular attention in Europe. We will discuss the latitude and longitude aspects for various regions of the world, and discuss the expected QoS levels using conventional SDARS satellite and repeater architectures.","PeriodicalId":221214,"journal":{"name":"2010 5th Advanced Satellite Multimedia Systems Conference and the 11th Signal Processing for Space Communications Workshop","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123453517","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 paper presents the results of finding good puncture-constrained dithered relative prime interleavers along with data puncture patterns to provide the required performance. A tradeoff between waterfall and flare performance can be made by selecting the best puncture masks for the required error rate. The performance of the turbo code with a packet size of 1504 data bits is presented for the following modulations: BPSK, QPSK, 8 PSK and 16 APSK. A comparison with other coding strategies shows that this code is an attractive option for use in a return satellite link application using adaptive coding and modulation.","PeriodicalId":221214,"journal":{"name":"2010 5th Advanced Satellite Multimedia Systems Conference and the 11th Signal Processing for Space Communications Workshop","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124465829","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 the proposed compensation scheme, we jointly estimate channel and phase noise and data. This estimation consists of three stages. In the first stage, phase noise, channel and transmitted data are initially estimated by using of linear interpolation method. In the second stage, with Linear Least Square Estimation (LLSE) method, phase noise and data estimation are updated to obtain more accurate estimation. Decision Feedback is applied in the third stage. It is shown by computer simulations that the proposed scheme can effectively mitigate the phase noise and improve the bit error rate of OFDM systems.","PeriodicalId":221214,"journal":{"name":"2010 5th Advanced Satellite Multimedia Systems Conference and the 11th Signal Processing for Space Communications Workshop","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116184384","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 consider a MIMO satellite link with focus on the Line-of-Sight (LOS) signal component of the MIMO channel between two geostationary satellites and a mobile earth terminal equipped with several antennae. The MIMO LOS channel is optimized with respect to the maximum achievable spectral efficiency. The aim of our approach is to keep this optimum spectral efficiency nearly constantly even if the terminal on earth is moving. We provide an analytical derivation for the optimum UCA arrangement and prove our results by numerical simulations. Especially for mobile applications, the UCA antenna arrangement seems to be a reasonable candidate in order to guarantee high capacity performance durably. To this end, we present a very simple triangle shaped antenna arrangement which is compact enough to allow vehicle roof top installations for S-band applications.","PeriodicalId":221214,"journal":{"name":"2010 5th Advanced Satellite Multimedia Systems Conference and the 11th Signal Processing for Space Communications Workshop","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116004416","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}
