The novel approach to the closed-form average bit error rate calculation for the Nakagami-m fading channel

A New Generalized Closed Form Expression for Average Bit Error Probability Over Rayleigh Fading Channel

Except for a few simple digital modulation techniques, derivation of average bit error probability over fading channels is difficult and is an involved process. In this letter, curve fitting technique has been employed to express bit error probability over AWGN of any digital modulation scheme in terms of a simple Gaussian function. Using this Gaussian function, a generalized closed form expres...

Bit Error Rate Analysis for MC-CDMA Systems in Nakagami-m Fading Channels

Multicarrier code division multiple access (MC-CDMA) is a promising technique that combines orthogonal frequency division multiplexing (OFDM) with CDMA. In this paper, based on an alternative expression for the Q-function, characteristic function and Gaussian approximation, we present a new practical technique for determining the bit error rate (BER) of multiuser MCCDMA systems in frequency-sel...

Bit Error Rate Analysis in WiMAX Communication at Vehicular Speeds using modified Nakagami-m Fading Model

Bit Error Rate Analysis of Mobile Communication Network in Nakagami Fading Channel: Interference Considerations

HERE is a steady rise in the number of mobile system users in the recent times. In order to accommodate more users in a given bandwidth, the spectral efficiency needs to be improved. So, frequency reuse technique is being adopted to increase spectral efficiency [1]. However, frequency reuse causes inter channel and co-channel interference which is more than additive white Gaussian noise of many...
