Ratios of input vectors detecting each syndrome (green: no-error, blue: single-error, red: double-error) in the (64,57,4)2 TPC according to the SNR regions when error correction is performed based on the Chase-Pyndiah algorithm. a SNR 1.0 dB corresponding to BER 10−1. b SNR 2.75 dB corresponding to BER 10−2. c SNR 3.25 dB corresponding to BER 10−4. d SNR 3.5 dB corresponding to BER 10−6
