| 摘 要： | 提出一种多入多出（M/MO）系统中的自适应空时比特编码调制方案（ST-ABICM）。本方案结合功率、比特分配及比特交织，在满足发射端吞吐量和总功率要求的条件下，使系统的误码率最小。为解决在快衰落信道中比特交织时延和可变速率编码之间的矛盾，提出与删除码结合的空时多层交织器，在实现比特交织的同时，不破坏编码比特位和删除位的位置。在接收端，我们提出一种比特连续干扰抵消（SIC）检测算法，这种算法相比最大似然算法大大降低了运算复杂度。

| Abstract: | An adaptive space-time bit interleaving coded modulation (ST-BICM) scheme was proposed in MIMO system. Combining with power allocation, bit allocation, and bit interleaving, this system minimized the system BER under constant data throughput. An ST multilevel puncturing scheme was adopted to solve the problem of symbol-by-symbol adaptive puncturing and interleaving. In receiver, a successive interference cancellation (SIC) receiver was proposed, which has a lower computer complexity comparing to ML. |
