Abstract

Abstract: The energy calculation of the noncoherent despreading/demodulation signal was extended into vector norm calculation based on the equivalence property theory of vector norm in the orthogonal codes spread spectrum system. Because the different kinds of norms need the different computation and complexity, we should choose the most suitable vector norm to process the despreading signals for simplifying the hardware circuit. Finally, we discussed the FPGA designs of three kinds of noncoherent despreading/demodulation signal processing units, which were realized by the 2-norm method, 1-norm method and ∞-norm method respectivel, and then offered their BER curves.

Key words: orthogonal codes spread spectrum, noncoherent despreading/demodulation, norm, FPGA
