A system and method is provided for improved frequency error estimation in a high- frequency data communication system. In an embodiment, a method for providing improved frequency error estimation comprises performing encoding, interleaving and symbol mapping on original information bits to form a data stream of modulated information symbols; inserting pilot symbols into the data stream at progressively longer time intervals and transmitting the data stream as a radio signal from a data transmitter to a receiver. The method further comprises using the received pilot symbols, transmitted at progressively longer time intervals to perform frequency error estimation. In certain embodiments, the received pilot symbols may also be used to perform improved channel estimation updates. |
