Chow
MIMO-OFDM系统中的自适应算法中的一种。Chow算法是根据各个子信道的信道容量来分配比特的。与Hughes-Hartogs算法相比,没有了大量的搜素和排序,简化了算法复杂度。(MIMO- OFDM systems in one of the adaptive algorithm. Chow algorithm is based on the channel capacity of each channel to allocate bits. Compared with Hughes- Hartogs algorithm, not a lot of search and sorting, simplify the algorithm complexity.)
