The invention relates to a method and apparatus for digital communications that provides high data rate wireless connections with bandwidth efficiency. The creation of multiple channels (that share the same time-frequency region) between the transmitter and the receiver is achieved by sampling the wavefield space with respect to the spatial domain. The wavefield space is the space spanned by the channel parameters that characterize the multipath fading environment. At the transmitter, symbols are simultaneously modulated and transmitted using signals that occupy the same frequency portion of the spectrum, but are distinguishable because different is their position in the wavefield space. The received signals are optimally processed to extract the digital information. The optimum demodulator estimates the wavefield space parameters without any training sequence or signal and performs optimum separation of the different signals to obtain the multiple streams. The throughput of such communication system is an integer multiple of the throughput that is achievable at each different position in the wavefield space. Given a perfect estimate of the wavefield space parameters, the Maximum Likelihood principle is the optimum strategy for detection. When the wavefield space parameters are a-priori unknown, the Maximum Likelihood detector can not be implemented. The invention describes the use of a focused wavelet-based model in the statistic of the detector which results in an effective approach to wavefield space demodulation without training signals or sequences in frequency selective multipath fading with arbitrarily time-varying fading characteristics.
