In this paper, bit error rate (BER) of the secondary cognitive system is studied using three different receivers: I) soft
Viterbi decoder only, II) optimal MMSE detector only and III) combining soft Viterbi decoder and MMSE detector. The results
show that the combined optimal MMSE detector and soft Viterbi decoder in the cognitive receiver removes the effects of the strong interference substantially at the low signal-to-noise ratio (SNR) region.
