Performance Analysis of Coherent TCM Systems with Diversity Reception in Slow Rayleigh Fading
Coherent trellis-coded modulation (TCM) systems employing diversity combining are analyzed. Three different kinds of combining are considered: maximal ratio, equal gain, and selection combining (SC). First, the cutoff rate parameter is derived for equal gain combining (EGC) and SC assuming transmission over a fully interleaved channel with flat slow Rayleigh fading, which permits comparison wit...
متن کاملPerformance of multiuser diversity reception in Rayleigh fading CDMA channels
Error probability of an adaptive multiuser diversity receiver is evaluated in terms of channel fading rate and the number of code-division multiple access users. Fading-induced performance loss, which leads to error probability floor, is established for the proposed coherent combining scheme and compared to that of differentially coherent receiver with equal-gain combining.
متن کاملComments on “New Method of Performance Analysis for Diversity Reception With Correlated Rayleigh-Fading Signals”
The purpose of this comment is to provide a critical discussion of the new method of performance analysis of diversity systems proposed in the abovementioned paper. It is shown that this method provides incorrect results for equal-gain and selective combining. A new method of performance analysis of two-branch receive diversity systems has been presented in the paper mentioned above.1 The main ...
متن کاملOn the Diversity Reception with Correlated Rayleigh-fading Signals
In this paper, the diversity reception with correlated Rayleigh fading signals will be investigated . Results will be evaluated by converting two correlated Rayleigh fading signals into another two independent Rayleigh fading signals using transformation matrix. These results show that Optimum transformation matrix F=1 is better than F = 2 / 2 which is the elements of the optimum transformation...
