On Channel Estimation of OFDM-BPSK and -QPSK over ... - CORE
This paper evaluates the performance of OFDM - BPSK & -QPSK based system with and without channel estimation over Nakagami-m fading channels. Nakagami-m variants are generated by decomposition of Nakagami random variable into orthogonal random variables with Gaussian distribution envelopes....

On Channel Estimation of OFDM-BPSK and -QPSK over ...
This paper evaluates the performance of OFDM-BPSK and -QPSK system in α-µ distribution. A fading model which is based on the non-linearity present in the propagation medium is utilized here for generation of α-µ variants. Different combinations of α and µ provides various fading distributions, one of which is Weibull fading....
Channel Estimation of MIMO–OFDM System Using PSO and GA ...
Thus, we propose a hybrid technique that includes particle swarm optimization (PSO) and genetic algorithm (GA) for channel estimation in MIMO–OFDM systems. The technique performs the conventional LS and MMSE channel estimation followed by enabling a fine tuning on the obtained channel model.
Derivation of BPSK BER in Rayleigh channel
my topic is walsh coded time domain mimo channel estimation.i face difficulty in programing of multipath rayleigh fading channel.in this their are 2 transmitter and 2 receiver and 6 path rayleigh fading channel.so in the paper delay and gain for 6 path is given for transmitter 1 to receiver 1 ,transmitter 2 to receiver 1 ,transmitter 1 to receiver 2 ,transmitter 2 to receiver 2.i can not do ......
Approximate SER for M-PSK using MRC and STTD Techniques ...
for i.i.d slow-flat Nakagami-m fading channel. Here, the MGF based analytical method was used to analyze this model using both transmit and receive antenna selection (TAS/RAS). Moreover, the outage and BER analysis of the MRC for band-limited BPSK system with micro-cellular system over i.i.d Rayleigh and Nakagami-m slow-flat fading channels were...
Performance analysis of modulation diversity with OSTBC ...
5. Conclusion. In this paper, performance of OSTBC system with modulation diversity has been analyzed over Nakagami-m fading channels for arbitrary m and numbers of transmit and receive antennas.Exact and closed-form PEP expression, which provides a union bound for SEP, has been derived.
BER PERFORMANCE ANALYSIS OF OFDM-BPSK, QPSK, QAM OVER ...
BER Performance Analysis of OFDM-BPSK, QPSK, QAM Over Rayleigh Fading Channel & AWGN Channel 3 size q, a block length n < q, and a message length k < n. In addition, the alphabet is deduced as the finite field of order q. q has to be a prime power. In the most useful parameterizations of the Reed–Solomon code,...
