Patent ID: 7095996

Claim:
A wireless transmitter for transmitting a signal to a wireless receiver, comprising: an encoder for encoding the transmission signal; a pre-modulation buffer for storing the encoded transmission signal; a modulator for modulating the encoded transmission signal in accordance with one of a plurality of modulation schemes which define a first number of transmission bits, which is the number of transmission bits per symbol in said wireless transmitter, to be equal to or smaller than a second number of transmission bits which is a previously defined number of transmission bits per symbol; and a RF module for transmitting the modulated transmission signal, wherein: information on said second number of transmission bits is shared with said wireless receiver; the transmission signal is read from said pre-modulation buffer every said second number of transmission bits and inputted into said modulator; and said modulator modulates said first number of transmission bits of the transmission signal inputted thereto, and does not modulate the remaining bits of the transmission signal which is the difference between the second number of transmission bits and the first number of transmission bits.
