METHOD AND APPARATUS OF IMPROVED CIRCULAR BUFFER RATE MATCHING FOR TURBO-CODED MIMO-OFDM WIRELESS SYSTEMS |
摘要 |
<p>Methods and apparatus for determining the starting points of redundancy versions in a circular rate matching operation. At least one block of information bits to be transmitted are encoded, then segmented into a plurality of sub-blocks of coded bits. The interleaved coded bits of the plurality of sub-blocks are collected and filled into a circular buffer having a plurality of redundancy versions in the circular buffer, with each redundancy version corresponding to a starting bit index in the circular buffer. For each transmission, a subset of bits is selected from the circular buffer by selecting a redundancy version. The selected subsets of bits are modulated, and are transmitted via at least one antenna. The redundancy versions, the number of bits between the starting point of a first redundancy version and the starting point of a second redundancy version is not divisible by at least one modulation order.</p> |
