| Abstract(in English) | The performance of square-law detection for code shift keying (CSK) is investigated in this report. In multipath channels, the delay signals become interference components, and they cause severe performance degradation. In spread spectrum (SS) systems, the interference of the delay signal can be reduced by spreading the transmit bandwidth. In conventional SS systems that use one spread code, the interference due to the multipath mainly depends on the auto-correlation property of the spread code. Since the CSK modulates the signal by using a code according to the information bits, it has similar characteristics of the SS systems. However, in the CSK, the effect of the delay signal depends on both auto- and cross-correlation properties of the code set because the CSK uses a code set which contains multiple codes. The average bit error rate performance in the multipath channel when the signal is detected by square-law detection is analyzed, and it is shown that the system using the code set having low auto- and cross-correlation properties has better performance than other systems. |
