产生Walsh函数序列的一种新方法

A New Method of Generating Walsh Functional Sequence

由于正交误差是影响walsh函数序列的重要指标 ,文中介绍了一种能完全避免正交误差的Walsh函数序列的新型产生方法 .首先讨论Walsh函数序列的哈达玛矩阵表示形式 ,然后讨论Walsh函数序列发生器的设计 ,阐述了该设计的理论依据 ,最后利用VHDL语言对其进行了软件仿真 .结果表明 ,此方法切实可行 ,可以使设计过程大为简化 。

The expression of Hadamard matrix is discussed for Walsh functional sequence,and then the design of Walsh functional sequence generator, and finally,simulation of softwave was made using VHDL Language.The results show that the new method can simplify the design and avoid the orthogonality errors of Walsh function sequence completely.
