Average Symbol Error Rate of Maximal Ratio Combining Scheme in the Presence of Multiple Cochannel Interferers
نویسندگان
چکیده
The performance of digital cellular radio systems with maximal ratio combining (MRC) diversity is analyzed in a flat-fading channel with cochannel interference and additive white Gaussian noise (AWGN). It is assumed that the desired signal may experience Rice fading while the Rayleigh-faded interferers may have similar or dissimilar average mean powers. Closed-form expressions are derived for the average error probability in the presence of multiple independent Rayleigh-faded interferers. Both binary and M-ary linear modulation schemes are considered. The analysis is also extended to the case when the desired signal has a Rice distribution.

Performance of generalized selection combining for mobile radio communications with mixed cochannel interferers
The performance of generalized selection combining (GSC) space diversity for mobile radio systems in the presence of multiple cochannel interferers is studied. Two cochannel interference models are considered: 1) cochannel interferers consisting of Nakagamiinterferers and Rayleigh interferers and 2) cochannel interferers in which each interferer follows Nakagamidistribution for a fraction of ti...

We derive an upper bound and investigate some approximations on the symbol error probability (SEP) for coherent detection of -ary phase-shift keying, using an array of antennas with optimum combining in wireless systems in the presence of multiple uncorrelated equal-power cochannel interferers and thermal noise in a Rayleigh fading environment. Our results are general and valid for an arbitrary...

We derive a simple closed-form upper bound on the symbol error probability for coherent detection of M -ary PSK using an array of antennas with optimum combining. We assume multiple equal-power cochannel interferers and thermal noise in a Rayleigh fading environment. The new bound applies for an arbitrary number of antenna elements as well as arbitrary number of interferers, and it is proved to...
