摘要：
In a remote unit receiver capable of demodulating a plurality of signal instances corresponding to a singe remote unit transmitted signal, a first instance of a signal is demodulated to produce a first set of energy values corresponding to a set of possible data values of the signal. A second instance of the signal is demodulated to produce a second set of energy values corresponding to the set of possible data values. The first and the second sets of energy values are then combined to determine a combined set of energy values. A first estimate of a most likely transmitted data value is determined based upon the combined set of energy values An energy level of the first instance is determined based upon the energy value within the first set of energy values corresponding to the first estimate of the most likely transmitted data value.
