Claim:
1. A transmitter system, comprising: an interface configured to receive data for wireless radio frequency transmission to a receiver system; a modulator configured to encode a first data portion of the data to generate a first pilot data symbol set for a first wireless radio frequency transmission to the receiver system, the first pilot data symbol set including first pilot data symbols at a first pilot data resolution, configured to encode a plurality of second data portions of the data to generate a plurality of non-pilot data symbol sets for a plurality of second wireless radio frequency transmissions to the receiver system, each non-pilot data symbol set including non-pilot data symbols at a non-pilot data resolution greater than the pilot data resolution, configured to encode a third data portion of the data to generate a second pilot data symbol set for a third wireless radio frequency transmission to the receiver system, the second pilot data symbol set including second pilot data symbols at a second pilot data resolution that is lower than the non-pilot data resolution, and configured to generate a pilot dataless symbol set for a fourth wireless radio frequency transmission to the receiver system, the pilot dataless symbol set including pilot dataless symbols at a pilot dataless symbol resolution; and an interface configured to communicate the first pilot data symbol set at the first pilot data resolution over the first wireless radio frequency transmission to the receiver system, configured to communicate the plurality of non-pilot data symbol sets each at the non-pilot data resolution over the plurality of second wireless radio frequency transmissions to the receiver system, and configured to communicate the second pilot data symbol set at the second pilot data resolution over the third wireless radio frequency transmission to the receiver system, the receiver system configured to use at least one of the first pilot data symbols in the first pilot data symbol set to generate a first phase error correction value for use in decoding the non-pilot data symbols of the plurality of non-pilot data symbol sets at the non-pilot data resolution, the receiver system further configured to use at least one of the second pilot data symbols of the second pilot data symbol set to generate a second phase error correction value for use in decoding subsequent non-pilot data symbol sets and the receiver system further configured to use at least one of the pilot dataless symbols in the pilot dataless symbol set to generate a third phase error correction value for use in decoding subsequent non-pilot data symbol sets.
