Abstract
This letter compares pilot-aided phase-shift keyed (PSK) and differential P SK (DPSK) modulation when using new maximum a posteriori joint channel esti mation and equalization receivers with frequency-selective fast-fading chan nels, We conclude that pilot-aided PSK has superior bit-error rate performa nce in this case, Howerer, at low signal-to-noise ratio, performance is sim ilar, and DPSK is competitive due to reduced receiver complexity.
