An effective receiver is achieved for situations where the receiver is mobile, and may be traveling at relatively high speed, and where the receiver's internal demodulation oscillator causes a frequency offset, with processing that shares a common algorithm for both frequency offset and channel characteristics estimations. Specifically, the commonly employed algorithm, such as the LMS algorithm, computes an estimate of the frequency offset, and that very same algorithm is also used to estimate the channel characteristics. When the LMS algorithm is used, a frequency offset estimate can be derived from signals derived in the course of executing the LMS algorithm. A frequency compensation factor is then developed and applied to the incoming signal to create a signal that that not have an appreciable frequency offset. That signal is then applied to a process that also employs the LMS algorithm, in combination with a detection algorithm, such as, for example, the Viterbi algorithm, to recover from the incoming signal the information signals that had been encoded into the incoming signals.
