BIT PARSER FOR INTERLEAVER IN TRANSMITTER WITH MULTIPLE TRANSMIT ANTENNAS

摘要

A transmitter having two or more transmit antennas includes a bit parser for providing two or more data streams to an interleaver of the transmitter. The bit parser receives bits representing data to be transmitted over the transmit antennas, and parses the bits into a number of data streams equal to a number of the transmit antennas such that the bits are divided into bit groups, each having no more than two of the bits, and each of the data streams include non-adjacent ones of the bit groups.

主权项

1. A wireless communication device comprising:
a plurality of antennas configured to transmit a plurality of transmission streams to another wireless communication device respectively via the plurality of antennas, wherein a first transmission stream is transmitted via a first antenna, a second transmission stream is transmitted via a second antenna; and a parser configured to:
receive a block of outbound data bits intended for transmission to the another wireless communication device via the plurality of transmission streams;divide the block of outbound data bits into a plurality of bit groups, wherein each respective bit group is formed from a same number of different consecutive bits from the block of outbound data bits, and the plurality of bit groups includes a first bit group adjacently followed by a second bit group and also includes a third bit group adjacently followed by a fourth bit group;generate and output a first data stream for first interleaving to generate the first transmission stream, wherein the first data stream includes the first bit group adjacently followed by the third bit group; andgenerate and output a second data stream for second interleaving to generate the second transmission stream, wherein the second data stream includes the second bit group adjacently followed by the fourth bit group, and each of the first data stream and the second data stream excludes any adjacent bit groups of the plurality of bit groups formed from the block of outbound data bits.
