Chip Interleaving and its Optimization for PAPR Reduction in MC-CDMA

Abstract

This paper analyzes the usability of peak to average power ratio (PAPR) reduction in multicarrier code division multiple access (MC-CDMA) by the chip interleaving optimization. This means chip position formatting to PAPR minimization. One chip interleaving pattern is used for all users in system (all spreading sequences). Dependency on number of subcarriers and spreading sequence length is simulated. The impact on amplitude histogram is presented and relation to random interleaving pattern is shown
