摘要

本文研究了基于BSOFDM的高阶旋转扩展矩阵的不同角度。之前的研究表明，当块大小为M = 2时，角度a = pi/3在UWB信道中获得了最佳的误码率。我们发现，当高阶旋转扩散矩阵用于较大的M大小的块时，情况就不再是这样了，其他角度产生的结果更好，这证明了旋转扩散矩阵比现有的扩散矩阵(如Hadamard)的优势在于它适应不同通信系统的灵活性。

A Study of Different Angles for Higher Order Rotation Spreading Matrix for BSOFDM in UWB Channels

This paper presents a study into different angles for higher order rotation spreading matrix developed for BSOFDM. It was shown previously that for block size M = 2 that the angle a = pi/3 achieved the best result in terms of BER in UWB channels. It was discovered that this was no longer the case when the higher order rotation spreading matrix was used for larger M sized blocks and that other angles produced better results which proves that the rotation spreading matrix advantage over existing spreading matrices such as the Hadamard is its flexibility to be adapted to different communication systems.
