- We propose a method for jointly performing timing recovery and turbo equalization on partial response channels with error-correction codes. The proposed detector uses soft decisions from previous turbo iterations to improve timing estimates before the next, and each iteration is only marginally more complex than that of a conventional turbo equalizer. As compared to a conventional receiver with separate timing recovery and turbo equalization at BER=2/spl times/10/sup -5/, the proposed receiver is superior by 4.7 dB in SNR with a rate-1/4 outer code, and by 2 dB with a rate-8/9 outer code.
