The throughput of a communication system using multiphase differential phase shift keying (DPSK) is a function of the bit error rate versus transmission speed for DPSK. The bit error rate is further affected by the signal-to-noise ratio on the transmission lines. By monitoring the block error rate for data transmitted at a specific speed and switching from the normal speed to a lower speed when the block error rate exceeds a predetermined value, the throughput of the transmission link is improved.
