The Generation of High-Speed Binary Sequences from Interleaved Low-Speed Sequences
Chris Woodcock, P.A. Davies · IRE Transactions on Communications Systems · 1987
This paper deals with the theory of generating high-speed binary sequences by interleaving two lower speed sequences which are displaced by half a bit period with respect to each other. The interleaving can be carried out by using a high-speed switch which is clocked at twice the clock rate of the lower speed sequences or by modulo 2 addition of the displaced sequences. Starting from any binary sequence, we give a general theory for the derivation of the binary sequences which are to be interleaved to produce any required high-speed sequence. We also deal with the particular case ofm-sequences.
