Pre-scaling of initial channel estimates in joint detection

A joint detection system configured to perform joint detection of received signals, the joint detection system comprising:

• a programmable digital signal processor (DSP) configured to generate 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, determine 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 pre-scale the at least one of the plurality of initial channel estimates by the at least one pre-scaling factor, wherein the programmable DSP is configured to determine a different pre-scaling factor for each differentinitial 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 the programmable DSP is configured to pre-scale 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.
