Abstract :
This paper proposes a hybrid method of uplink ACK/NACK signaling combining the advantages of both the non-coherent and the coherent methods. Simulations show that the proposed method improves the SNR performance by about 1 dB at the BER of 10-4 when compared with the coherent methods, with little loss in actual multiplexing capacity.
