| 摘 要： | 将尾抵消和循环重建应用于空频编码的正交频分复用（SFBC-OFDM）系统中，为了消除循环前缀对空频编码带宽损失的影响，使用了迭代算法来校正接收到的信号．由于采用了尾抵消和循环重建，较之传统的带有循环前缀的空顿编码，带宽效率得到了很大的提高．仿真结果显示，该方法在迭代次数很小时性能便可接近带有循环前缀的SFBC-OFDM系统．

| Abstract: | Tail cancellation and cyclic reconstruction are applied in SFBC-OFDM system to eliminate the bandwidth loss of space-frequency coding due to the cyclic prefix. Iterative algorithm is used to rectify the received signal. Bandwidth efficiency is greatly improved because of the use of tail cancellation and cyclic reconstruction. Simulation results show that this algorithm can approach approximately the SFBC-OFDM with cyclic prefix even if the number of iteration is very small. |
