BER performance of OFDM-MDPSK system in frequency-selective Rician fading with diversity reception
A closed form formula is derived for the bit error rate (BER) of orthogonal-frequency-division-multiplexing (OFDM) with -ary differential-phase-shift-keying (MDPSK) systems in frequency-selective Rayleigh and Rician fading channels with diversity reception. New BER curves are obtained as a function of the rms delay spread of the diffused component for three different types of delay profiles: 1)...
متن کاملProbability of symbol error for MPSK, MDPSK and noncoherent MFSK with MRC and SC space diversity in - Wireless Communications and Networking Confernce, 2000. WCNC. 2000 IEEE
This paper derives analytically some simple closed form expressions for the average symbol error rate (SER) of M-ary phase shift keying (MPSK), M-ary differential phase shift keying (MDPSK) and noncoherent Mary frequency shift keying (MFSK) over a Nakagami-m fading channel with Lfold maximal ratio combining (MRC) and selection combining (SC) space diversity receptions. Numerical results demonst...
متن کاملNew exponential bounds and approximations for the computation of error probability in fading channels
We present new exponential bounds for the Gaussian function (oneand two-dimensional) and its inverse, and for -ary phase-shift-keying (MPSK), -ary differential phase-shift-keying (MDPSK) error probabilities over additive white Gaussian noise channels. More precisely, the new bounds are in the form of the sum of exponential functions that, in the limit, approach the exact value. Then, a quite ac...
متن کاملBER Performance of OFDM System in Frequency-Selective Rician Fading with Diversity Reception
In this paper, we theoretically study the bit error rate (BER) performance of OFDM systems with MDPSK modulation for subchannels in frequencyselective flat Rician fading and additive white Gaussian noise (AWGN). Both the Rayleigh and Rician fading conditions are considered. The differential detection technique is used to avoid the need of a complex equalization process. Circular prefixes are ad...
متن کاملA new, simple, and exact union bound for reference-based predetection and postdetection diversity TCM-MPSK systems in Rayleigh fading
Trellis-coded modulation (TCM), when combined with interleaving of sufficient depth, is known to provide some form of time diversity that allows for the achievement of good error performance in fading environments. Also, space diversity reception, in which several signals received at different antennas are combined, is a well-known method that can be used to combat the effects of fading in wire...
