摘要： In a multi-carrier communication system employing adaptive modulation and coding, a receiver feeds back channel quality information for a “binned” group of subcarriers instead of sending an individual quality report for each subcarrier. A transmitter will utilize the channel quality information for the bin to determine a set of γeff values corresponding to a set of modulation and coding scheme candidates, where γeff is an effective SNR that would yield a same FER in an AWGN channel. The transmitter utilizes the set of γeff values to aid in determining a modulation and coding scheme, and determine a single modulation and coding scheme for all subcarriers within the channel.

摘要： A method and apparatus for rate matching is described. During operation of a transmitter, multiple data streams are received and individually interleaved with a permutation of a same length KΠ. A permutation (πp0) of a second stream is the same as a permutation (πsys) of a first stream and a permutation (πp1) of a third stream is different from the permutation of the first stream. Each element of πp1 is derived from the corresponding element of πsys. The plurality of interleaved streams are multiplexed to form a circular buffer. Finally, data is transmitted from the circular buffer.

摘要： A method and apparatus for decoding data is provided herein to show how to turbo decode LDPC codes that contain a partial dual diagonal parity-check portion, and how to avoid memory access contentions in such a turbo decoder. During operation, a decoder will receive a signal vector corresponding to information bits and parity bits and separate the received signal vector into two groups, a first group comprising signals corresponding to the information bits and one or more parity bits, a second group comprising a remainder of the parity bits. The first group of received signals is passed to a first decoder and the second group of received signals is passed to a second decoder. The decoders are separated by an interleaver and a deinterleaver. Iterative decoding takes place by passing messages between the decoders, through the interleaver and the deinterleaver, and producing an estimate of the information bits from the output of the first decoder.

摘要： A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.

摘要： A method and apparatus for selecting interleaver sizes for turbo codes is provided herein. During operation information block of size K is received. An interleaver size K′ is determined that is related to K″, where K″ from a set of sizes; wherein the set of sizes comprise K″=ap×f, pmin≦p≦pmax;fmin≦f≦fmax, wherein a is an integer and f is a continuous integer between fmin and fmax, p takes integer values between pmin and pmax, a>1, pmax>pmin, pmin>1. The information block of size K is padded into an input block of size K′ using filler bits, if needed.
