This paper gives some properties of companion matrix of polynomial over finite field with its application for evaluating period of linear shift register sequence and minimal length of cyclic code.
It is shown that the phase noise spectrum density shift periodicity with the length of external cavity and the peak value of power spectrum density varies considerably with the feedback coupling rate.
