Bit Error Rate Analysis for OFDM Systems for MRC Receivers in Nakagami- m Fading Channel Generated by Using Rayleigh and Ricean Fading

Error rates of orthogonal frequency division multiplexing (OFDM) signals are considered for system using multichannel reception with maximum ratio combining (MRC) receivers in Nakagami-m fading generated by sum of sinusoidal method using Rayleigh and Ricean channel. The paper also discusses the effect of frequency offsets, nakagami-m parameter m on OFDM systems. Also effect of frequency offset on signal to noise plus interference ratio (SINR) for different SNR values is discussed. A closed form expression for probability of error is derived and theoretical and simulated results are compared for various receivers, frequency offsets.
