Error probability for optimum combining of M-ary PSK signals in the presence of interference and noise
An exact expression for the symbol-error probability (SEP) for coherent detection of -ary phase-shift keying using an array of antennas with optimum combining in a Rayleigh fading environment is derived, based on the theory of orthogonal polynomials. In particular, performance analysis in the presence of multiple uncorrelated equal-power cochannel interferers and thermal noise is considered, st...
متن کاملSymbol Error Performance Analysis and Comparison between Alamouti and MRRC Diversity Combining Scheme for Wireless Communication
The symbol error performance of a wireless communication system is analyzed using diversity combining scheme in Rayleigh fading channels. The performance of the system is compared using Alamouti scheme and maximal-ratio receiver combining (MRRC) scheme. The performance results of the system are evaluated by numerical computation and by simulation using MATLAB. A detailed analysis and exact (clo...
متن کاملEfficient Method for APSK Demodulation
In the new digital video broadcasting standard using satellites, denoted as DVB-S2, 16-ary and 32-ary amplitude-phase shift keying APSK are applied as modulation techniques. Optimum decision algorithms for 16-APSK and 32-APSK resulting from Voronoi diagrams demand relatively complicated hardware, typically high-capacity memories for demapping tables. In this paper, the efficient method based on...
متن کاملSimulink Based Comparative Analysis of M-ary Phase Shift Keying Modulation Schemes
This paper focuses mainly on Bit Error Rate(BER) and Signal to Noise Ratio(SNR).To analyse the system’s performance probability of error plays a major role. Each modulation technique has its own performance while dealing with signals corrupted with noise. This paper describes the comparative analysis of basic M-ary Phase Shift Keying modulation schemes like BPSK, QPSK,8-PSK and 16-PSK. It gives...
متن کاملAnalysis of -ary Phase-Shift Keying with Diversity Reception for Land-Mobile Satellite Channels
An analytical technique well suited to numerical analysis is presented for computing the average bit-error rate (BER) and outage probability of M -ary phase-shift keying (PSK) in the land-mobile satellite channel (LMSC) with microdiversity reception. Closed-form expressions are found for L-branch microdiversity using both selection diversity combining (SDC) and maximal ratio combining (MRC). Th...
