Parasitic Spectral Lines in High Speed Generation of Binary Maximum Length Sequences
C. Chamzas · IRE Transactions on Communications Systems · 1978
Adding modulo-2 a binary maximum length sequence to its replica delayed by half the maximal length,N, results in the same sequence but at twice the bit rate. The error in the spectral density of the resulting sequence which is created by delaying the replica by(N/2) + \epsiloninstead ofN/2is examined, and the analytical formulas are derived.
