| 摘 要： | 本文讨论了空时分组码的自适应调制技术.在接收端分集合并后的等效信道模型下,通过对自适应STBC信道容量的讨论证明了随着天线数的增加,自适应调制的重要性降低.之后针对二发一收的低价分集系统,讨论了其STBC基础上的自适应调制技术,同时给出了离散功率离散速率自适应调制区间端点的封闭解.

| Abstract: | The adaptive modulation on STBC is considered in this paper. Through using the equivalent channel model of receiver end after diversity combine, we prove that the significance of adaptive modulation depresses while antenna number is increased. After that the adaptive modulation technique is discussed for low diversity system of 2 transmit an 1 receiver based on STBC, and a closed solution of interval endpoint is given for discrete power and discrete rate adaptive modulation system. |
