Claim One:
1. A method for communicating data symbols in a network, comprising: transmitting, by a transmitter via a channel, data symbols using modulation of a block code for non-coherent transmission; modeling the channel using the space-time-frequency basis expansion to represent inter-symbol interference (ISI) due to multi-path delays and inter-carrier interference (ICI) due to time-varying fading; approximating the channel by a dominant Karhunen-Loeve transform (KLT) basis vectors, wherein a Legendre polynomial basis may be used over a time domain, and a Fourier basis may be used over a frequency domain; and detecting a received signal, wherein the detecting uses a generalized likelihood ratio test (GLRT) with soft-in soft-out space-time-frequency basis expansion to reproduce the data symbols, wherein a multi-dimensional basis expansion model (BEM) is used.
