BASEBAND PROCESSOR WITH LOOK-AHEAD PARAMETER ESTIMATION CAPABILITIES

摘要

In a receiver for receiving data samples including a sequence of symbol values transmitted across the channel, a baseband processor including a first hypothesize unit developing first sets of hypothetical symbol values, a second hypothesize unit developing second sets of hypothetical symbol values different from the first sets, a parameter estimator receiving the received data samples and the first and second sets of hypothetical symbol values and developing parameter estimates based thereon, and a sequence estimator receiving the developed parameter estimates, the first sets of hypothetical symbol values and a delayed version of the received data samples and developing a sequence of detected symbol values related to the received data samples.
