متن کاملLevel Crossing Rate of Macrodiversity System Operating over Gamma Shadowed Rician Fading Channel
Macrodiversity system with macrodiversity selection combining (SC) receiver and two microdiversity SC receivers is considered. Received signal is affected simultaneously to Gamma long term fading and Rician short term fading resulting in system performance degradation. Macrodiversity SC receiver reduces Gamma shadowing effects and microdiversity SC receivers reduce multipath fading effects on b...
متن کاملUpper Bounds on the BER Performance of MTCM-STBC Schemes over Shadowed Rician Fading Channels
Space-time block coding (STBC) provides substantial diversity advantages with a low decoding complexity. However, these codes are not designed to achieve coding gains. Outer codes should be concatenated with STBC to provide additional coding gain. In this paper, we analyze the performance of concatenated trellis-coded STBC schemes over shadowed Rician frequency-flat fading channels. We derive a...
متن کاملDirect-Sequence Spread Spectrum in a Shadowed Rician Fading Land-Mobile Satellite Channel
The performance of a direct sequence spread-spectrum land-mobile satellite transmission system, using binary phase shift keying (BPSK) modulation, is analyzed. The satellite channel is modeled as having shadowed Rician fading characteristics. The bit error probability is evaluated, considering both the envelope and the phase variation. Assuming a Gaussian approximation for the interference, num...
متن کاملEffect of Microdiversity and Macrodiversity on Average Bit Error Probability in Gamma - Shadowed Rician Fading Channels
© 2010 ETRI Journal, Volume 32, Number 3, June 2010 In this letter, we analyze the error performance of a mobile communication system with microdiversity and macrodiversity reception in gamma-shadowed Rician fading channels for a binary differential phase-shift keying modulation scheme. Analytical expressions for the probability density function (PDF) and moment-generating function (MGF) are de...
