摘要：

A closed form formula is derived for the hit error rate (BER) of orthogonal-frequency-division-multiplex (OFDM) with M-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) one-sided exponential, 2) uniform and 3) double spike profiles. Both slow and fast fading conditions are considered. It is shown that the existence of a strong line-of-sight (LOS) component and the use of reception diversity fan effectively improve transmission performance.
