摘要

本文比较了基带多输入单输出(MISO)超宽带系统(UWB)的性能，其中包含两种预失真:时间反转(TR)和约束最小二乘(CLS)预均衡器。对于CLS，提出了一个简单的代价函数，可以很容易地用基于梯度的算法求解。结果表明，CLS方案具有较好的码间干扰抑制效果，且计算复杂度适中。

MISO time reversal and constrained least squares pre-equalizer ultra-wideband systems

The paper compares the performance of a baseband multiple-input single-output (MISO) ultra-wideband system (UWB), incorporating two types of pre-distortion: time reversal (TR) and a constrained least squares (CLS) pre-equalizer. For the CLS, a simple cost function is proposed which can be easily solved with a gradient based algorithm. Results show that the CLS scheme provides a good inter-symbol interference (ISI) reduction, with a moderate computational complexity.
