Patent ID: 7924948

Claim:
In a joint detection system configured to perform joint detection of received signals, a method comprising: (A) generating a plurality of initial channel estimates corresponding to a plurality of propagation channels, wherein each of the plurality of initial channel estimates comprises a plurality of values; (B) determining at least one pre-scaling factor for at least one of the plurality of initial channel estimates, wherein the at least one pre-scaling factor is at least partially based on at least one of the plurality of values of at least one of the plurality of initial channel estimates; and (C) pre-scaling the at least one of the plurality of initial channel estimates by the at least one pre-scaling factor, wherein (B) comprises: determining a different pre-scaling factor for each different initial channel estimate of the plurality of initial channel estimates, wherein each different pre-scaling factor is at least partially based on at least one of the plurality of values of each different initial channel estimate, wherein (C) comprises: pre-scaling each different initial channel estimate by the different pre-scaling factor, respectively, such that each maximum absolute value of the plurality of values of each different initial channel estimate have the same exponent.
