- We introduce a rotational decision-directed joint algorithm of blind equalization coupled with carrier recovery for 32-QAM demodulation with high symbol rate. The propsed carrier recovery, which we call a rotational decision-directed carrier recovery(RDDCR), removes the residual phase difference by rotating the decision boundary for the kth received symbol by the frequency detector output of the (k-1)th received symbol. Since the RDDCR includes the function of PLL loop filter by rotating the decision boundary, it gives a simpler demodulator structure.The rotational decision-directed blind equalization(RDDBE) with the rotated decision boundary based on the Stop-and-Go Algorithm(SGA) operates during tracking the frequency offset by the RDDCR and removes intersymbol interference due to multipaths and channel noise.Test results show that symbol error rate of 10-3 is oftained before the forward error correction when SNR equals 15dB with 150KHz of carrier frequnecy offset and two multipaths, which is the channel condition for 32-QAM receiver.
