Simple spreading code allocation scheme for downlink MC-CDMA
- Simple spreading code allocation scheme for downlink MC-CDMA
final
- In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The rec

- 从多普勒载波频偏对CDMA接收 信号的影响入手，提出了分段匹配滤波器和循环累加码捕获环路相结合的方法进 行扩频码的捕获，并对该方法的性能进行了分析和仿真。 -Doppler frequency offset from the carrier signal on the CDMA receiver to start the impact of proposed sub-cycle accumulation matched filter code acquisition loop and
QPSK
- Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
