A lower bound analysis for bit error rate of trellis‐coded QPSK modulation in impulsive noise environment

The efficiency of trellis-coded modulation (TCM) schemes against Gaussian noise has been well known. However, its performance for impulse noises, which degrade the quality of urban radios, wire communications, and so on, remains unknown. This paper pays special attention to a trellis-coded QPSK modulation scheme, for example, and clarifies the analysis method of lower bounds of bit error rates. Also, computer simulations were made to verify the analytical results. As a result, the efficiency of the TCM scheme against the impulse noise has been clarified.
