| Abstract(in English) | Recently, the new spreading sequence obtained by Weyl sequence is proposed. Its crosscorrelation function follows O(1/N), where $N$ is the length of the sequence. In this report, we optimize the code design to assign to each user and we analytically calculate its theoretical SIR (Signal to Interference Noise Ratio). Our spreading sequence has about 2.5 times larger capacity of users than the Gold code. |
