Patent ID: 8059740

Claim:
A wireless local area network (WLAN) transmitter having high data throughput, the WLAN transmitter comprises: a baseband processing module operable in a plurality of 802.11 wireless communication modes of operation, wherein each of the plurality of 802.11 wireless communication modes of operation indicates one of a plurality of different set of values for frequency band, channel bandwidth and bit rate, wherein the baseband processing module is operably coupled to: receive data and a mode selection signal, wherein the mode selection signal selects one of the plurality of 802.11 wireless communication modes of operation that indicates the one of the plurality of set of values for frequency band, channel bandwidth and bit rate corresponding to the selected one of the plurality of 802.11 wireless communication modes of operation for the WLAN transmitter; scramble the data in accordance with a pseudo random sequence to produce scrambled data; select one of a plurality of encoding modes for the selected of 802.11 wireless communication mode of operation based on the mode selection signal; encode the scrambled data in accordance with the one of the plurality of encoding modes to produce encoded data; determine a number of transmit streams based on the mode selection signal; and convert the encoded data into streams of symbols in accordance with the number of transmit streams and the mode selection signal, wherein the converting the encoded data further comprises: interleaving the encoded data over multiple symbols and subcarriers of a channel to produce interleaved data; demultiplexing the interleaved data into a number of parallel streams of interleaved data, wherein the number of parallel streams corresponds to the number of transmit streams determined based on the mode selection signal; and processing each of the parallel streams of interleaved data to produce the streams of symbols, wherein the processing is based on the mode selection signal; and a plurality of radio frequency (RF) transmitters, wherein, based on the mode selection signal, a number of the plurality of RF transmitters are enabled, wherein each of the number of plurality of RF transmitters that are enabled converts a corresponding one of the streams of symbols into a corresponding RF signal such that a corresponding number of RF signals is produced within the frequency band and having the channel bandwidth and the bit rate corresponding to the selected of one of the plurality of 802.11 wireless communication modes of operation for the WLAN transmitter.
