  Abstract

A collision dispersion scheme based on orthogonal pre-spreading is proposed to reduce the effect of collisions that occur in orthogonal code hopping multiplexing(OCHM). The OCHM scheme was previously proposed to accommodate a significantly larger number of low-activity bursty channels than the number of orthogonal codewords. The proposed scheme greatly reduces the required SNR in channel decoding. In addition, the proposed scheme can be applied to OFHM based on OFDM.
