BER ANALYSIS OF WiMAX IN MULTIPATH FADING CHANNELS

In this paper, an effort has been made to inspect the performance of WiMAX OFDM physical layer under the effect of noise. An End-to-end baseband WiMAX OFDM physical layer has been modelled in Multipath fading environment using MATLAB Simulink. BER has been evaluated for the Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (16 QAM) and 64...

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

BER 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...

BER Performance Analysis of a FEC Encoded Multi-user MIMO MCCDMA Wireless Communication System

In this paper, we made a comprehensive study to evaluate the performance of a multi-user MIMO MCCDMA wireless communication system. The channel encoded spatially multiplexed MIMO MCCDMA system under investigation incorporates four linear signal detection schemes (Equalizers) such as Minimum Mean Square Error (MMSE), Zero Forcing (ZF), Sphere Decoding and Q-less QR Decomposition under BPSK, DPSK...

Performance of adaptive matched filter receivers over fading multipath channels

Various types of noise inherent in the channel estimation process for a fading multipath channel are examined and modeled. Performance degradation due to noisy channel estimation in the adaptive matched filter receiver is analyzed, and some numerical results-contrasting reference-directed and decision-directed channel estimation-are presented for the troposcatter channel.
