In [1], the use of the Fourier transform to eliminate intersymbol interference from time-invariant channels and the performance of a non-practical block coding scheme with long discrete Fourier transform length for high data-rate transmission were reported. This paper presents the performance of a practical trellis-coded block DQPSK scheme with short transform length in the presence of intersymbol interference. It is shown, by simulation, that the use of a short transform followed by cyclic extension does not degrade the performance, and is suitable for high-speed data transmission.
