摘要
本文在GF（2^2)域开发了Searle运算，并把它同GF（2）域的运算做了比较。用GF（2）域的Searle运算构成了一个GF（2^2)域的移位寄存器序列，给出了GF（2^2)域的Hadamard定序的快速Walsh-Fourier变换的显式公式。
Searle operations over GF(22)has been developed and the operations over GF (2) are compard with one over GF(22). A shift register sequence over GF(22) is generated by Searle operations and the explicit forms of Hadamard ordered 'Logical' Fast Walsh-Fourier Transform over GF(22) are given.
