| Abstract(in English) | DS-CDMA has been extensively investigated as a promising application to the future mobile radio access. Recently, we proposed coherent multicode DS-CDMA (CM-CDMA) that applies 2-layered spreading code assignment, pilot symbol-aided coherent detection, traffic-adaptive transmit power control and multicode transmission. This paper describes a CM-CDMA test-bed system and experimental results. It is confirmed that pilot symbol-aided coherent RAKE can reduce the required signal energy per bit-to-interference plus background noise spectrum density ratio (Eb/Io). Also shown is that by using both RAKE combining and SIR-based power control the transmit power of mobile stations can be significantly reduced. The performance of the multicode transmission using orthogonal Gold code is also clarified. |
