Analytical Error Rate Performance Evaluation of OFDM-QPSK System over Nakagami Distribution
Modern wireless communication system demands high data rate with acceptable error rate transmission and reception. OFDM a multi-carrier modulation technique will provide the solution for next generation wireless communication, so that it has been employed in numerous wireless standards. This paper presents new technique for the error rate of OFDM-QPSK system over Nakagami-m and Nakagami-n (Rice...
متن کاملBit Error Rate Performance of QPSK Modulation and OFDM-QPSK with AWGN and Rayleigh Multipath Channel
In this paper Bit Error Rate performance of QPSK modulation and OFDM -QPSK System over AWGN and Rayleigh fading channel is analyzed. The performance of BER of QPSK over AWGN and Rayleigh channel is compared. OFDM is an orthogonal frequency division multiplexing to reduce intersymbol interference problem. Simulation of QPSK signals is carried with both AWGN and Rayleigh channel. Finally simulati...

متن کاملOn Channel Estimation of OFDM-BPSK and -QPSK over Nakagami-m Fading Channels
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. Performance of OFDM system in Nakagami channel has been reported here. The results yield the optimum value ...
متن کاملBER Performance of OFDM-BPSK over Nakagami Fading Channels
In this paper, the Bit Error Rate (BER) performance of OFDM -BPSK system over flat Nakagami fading channels is analyzed. This model is versatile enough to represent fading. Here our approach is based on decomposition of Nakagami random variable into orthogonal random variables with Gaussian distribution envelopes. Finally simulations of OFDM signals are carried with Nakagami faded signal to und...
