Radio communication apparatus and method

A method for radio communication, comprising the steps of:

• detecting a symbol timing from a Nyquist point in detection-result data;
• controllably generating or non-generating a to-be-transmitted symbol or symbols at every detected symbol timing, converting the to-be-transmitted symbol or symbols into modulating data pieces, and outputting the modulating data pieces to a first FIFO buffer;
• reading out modulating data pieces from the first FIFO buffer at a predetermined rate and converting the read-out modulating data pieces into an analog modulating signal for use in modulation of a carrier;
• and
• controlling a number of the to-be-transmitted symbol or symbols generated at every detected symbol timing to hold a number of modulating data pieces in the first FIFO buffer in a predetermined range.

A radio communication apparatus comprising:

• means for repetitively detecting a symbol timing from a Nyquist point in detection-result data;
• a first FIFO buffer;
• means for controllably generating or non-generating a to-be-transmitted symbol or symbols at every detected symbol timing, converting the to-be-transmitted symbol or symbols into modulating data pieces, and writing the modulating data pieces into the first FIFO buffer;
• means for reading out modulating data pieces from the first FIFO buffer at a predetermined rate and converting the read-out modulating data pieces into an analog modulating signal for use in modulation of a carrier;
• and
• means for controlling a number of the to-be-transmitted symbol or symbols generated at every symbol timing to hold a number of modulating data pieces in the first FIFO buffer in a predetermined range.
