Over a channel, a signal including a desired portion associated with a desired channel and an undesired portion mixed with said desired portion may be received. Based on prior knowledge and/or empirical estimation of the desired channel and an empirical estimate of the signal cross-covariance, the desired portion from the received signal may be recovered by adaptively equalizing the channel. In one embodiment, a receiver 10, such as a mobile device e.g., a cellular phone includes a processor 75 operably coupled to a communication interface 15 including at least two antennas 55 to receive the signal. The receiver 10 may further include a MODEM 70 that may be operably coupled to the processor 75, that includes an adaptive equalizer 86 capable of detecting the signal in the presence of co-channel interference from several independent sources, inter-symbol interference and fading, for recovering the desired portion in a cellular environment with time division multiple access TDMA to enable digital transmission of the signal. Thus, a blind adaptive space-time equalization on the signal based on minimum mean square error MMSE may be provided. |
