ABSTRACT:
Receivers and methods for receiving transmitted symbols are disclosed in which techniques are applied to jointly combat fading, time dispersion, and interference that is correlated in both space and time. These objects are accomplished by, for example, providing an inverse impairment correlation sequence estimate to the branch metric processor in addition to a channel estimate. The branch metric processor can then use this additional information to provide branch metrics that take into account the time correlation of impairment to improve the symbol hypotheses.
