Patent ID: 8248975

Claim:
A wireless transmitting apparatus comprising: a symbol generating circuit that converts a transmission data bit stream to a data symbol sequence; a training signal generating circuit that generates a training signal including information for carrier recovery, information for clock recovery, and information for frame synchronization; a multiplex circuit that multiplexes said training signal and said data symbol sequence, and generates a transmission burst signal; and a digital-to-analog conversion circuit that performs a digital-to-analog conversion of said transmission burst signal, wherein the training signal generated by said training signal generating circuit is inserted into a transmission burst as a pilot signal at fixed symbol intervals by said multiplex circuit, wherein said training signal generating circuit comprises: a synchronization code sequence generating circuit that generates a synchronization code sequence signal for frame synchronization; a differential encoding circuit that differentially encodes said synchronization code sequence signal; and an interleave circuit that interleaves said differentially encoded synchronization code sequence signal.
