摘要

本文讨论了自适应波束形成算法的设计，用于在多径和同信道干扰环境下提高时分多址(TDMA)信号的接收能力。提出了一个问题的公式，强调“现实世界”的问题，如帧同步和部分时隙重叠由于同信道干扰。研究了三种波束形成解调器结构及其性能自适应优化算法。仿真结果表明，与单天线系统相比，波束形成解调器结构可以显著提高误码率作为信噪比的函数。比较了各种结构的计算复杂度，证明在TMS320C40数字信号处理器上实现是合理的。

Adaptive beamforming for TDMA signals

This paper addresses the design of adaptive beamforming algorithms used to improve the reception of time division multiple access (TDMA) signals in an environment rich in multipath and co-channel interference. A formulation of the problem is presented with an emphasis on "real-world" issues such as frame synchronization and partial slot overlap due to co-channel interferers. Three beamformer-demodulator structures are examined along with algorithms for adaptively optimizing their performance. Simulation results are provided to show that the beamformer-demodulator structures can significantly improve the bit error rate as a function of the SINR compared to a single antenna system. The computational complexity of the various structures is compared and shown to be reasonable for implementation on a set of TMS320C40 digital signal processors.
