Abstract
A method for receiving transmissions includes receiving a first symbol-spaced baseband signal corresponding to first portions of first and second encoded data sequences transmitted over first and second baseband channels, and receiving a second symbol-spaced baseband signal corresponding to second portions of the first and second encoded data sequences transmitted over the first and second baseband channels. The first and second symbol-spaced baseband signals are combined to provide a combined baseband signal, and the combined baseband signal is prefiltered to provide minimum phase channel characteristics. The prefiltered combined baseband signal is equalized to provide an estimate of a data sequence. Related receivers are also discussed.
