• This paper is intended to provide reliable carrier recovery in environments with a very low C/N (carrier-to-nouse power ratio). A demodulation scheme using a carrier recovery circuit supported by frame symbols (CRC-PIDS) is proposed. This scheme uses a recovery order of clock, frame, and carrier, which is effective for carrier recovery in a low C/N channel, and enables coherent detection without differential coding. This paper also evaluates the bit-error-rate (BUR) performance of the proposed scheme used with a binary PSK signal with a rate-1/3 4-state turbo code. Computer simulation trials show that the BER performance difference between ideal and practical coherent detections is about 0.2 dB, and that carrier recovery is reliable even at a C/N of -4.8 dB.
