The Construction and Performance of a Novel Intergroup Complementary Code
Abstract: On the basis of the
analyses for intergroup complementary (IGC) code and zero correlation zone
complementary code, a novel IGC code has been proposed to adapt M-ary
orthogonal code spreading spectrum system or quasi-synchronous CDMA system. The
definition and construction methods of the new IGC codes are presented and an
applied example is given in this paper. Theoretical research and simulation
results show that the main advantages of the novel IGC code are as following:
The code sets of the novel IGC code is more than IGC code under the same code
length. The zero correlation zone length is longer than the intergroup IGC
code, but shorter than the intergroup IGC code. Under the same code length, the
auto-correlation performance of the novel IGC code is better than that of the
IGC code, and both are of similar cross-correlation performance.
Keywords: modified intergroup
complementary code, Matlab simulation, zero correlation zone code, generalized
orthogonal code
