| Abstract: | An algorithm for estimating the parameters of pseudorandom biphase-coded CW signals is presented. The carrier frequency and primary phase can be obtained via frequency multiplication to create a correlation receiver, whose output can be used to estimate the code element width and number as well as the code sequence. |
