PURPOSE: The pilot symbol assisted radiotelephone communications are provided to compensate fading and interference effect, to attain bit error rate without estimating filter and to relieve the decrease of information ability. CONSTITUTION: Radiotelephone communications are processed to produce a pilot symbol assisted modulation(PSAM) communications symbol sequence, including a plurality of predetermined pilot symbols interleaved with a plurality of information symbols. The pilot symbol assisted modulation communications symbol sequence is communicated over a radiotelephone communications channel having a transfer characteristic. Pilot symbol data, corresponding to pilot symbols, and information symbol data, corresponding to information symbols, are identified in the sequence of communications symbol data estimate of the transfer characteristic of the radiotelephone communications channel is generated from the pilot symbol data and the information symbol data.
