Patent ID: 8411789

Claim:
A radio communication apparatus comprising: a clock reproducer unit configured to repetitively detect a symbol timing from a Nyquist point in detection-result data; a first FIFO buffer; a symbol generator unit configured to controllably generate or non-generate a to-be-transmitted symbol or symbols at every symbol timing detected by the clock reproducer unit, convert the to-be-transmitted symbol or symbols into modulating data pieces, and output the modulating data pieces to the first FIFO buffer; a first D/A converter configured to read out modulating data pieces from the first FIFO buffer at a predetermined rate and convert the read-out modulating data pieces into an analog modulating signal for use in modulation of a carrier; and a controller unit configured to control a number of the to-be-transmitted symbol or symbols generated by the symbol generator unit at every symbol timing to hold a number of modulating data pieces in the first FIFO buffer in a predetermined range.
