Binary sequences with Large Family Size and High Linear Complexity for Spread Spectrum Communication Systems
Spreading sequences with low correlation, higb lin ear complexity and large family size, in a direct-sequence spread spectrum commumcation system, help to minimize multiple ac cess interference, increase security degree of system and enlarge user number, respectively. In this paper, a family of binary sequences with 5-valued low correlation, large family size and high linear complexity is presented. The proposed sequences have the same correlation distribution as the sequences in Ref. 6. and include the latter and No sequences as special cases. Although a closed-form mathematical expression regarding linear complexity of the proposed sequences can not be given, the simulation results by a computer show that the number of the proposed sequences, whose linear complexity is not less tban the highest that of the sequences in Ref 6, is quite larger than one of the sequences with the highest linear complexity in Ref. 6.
