| 摘 要： | The de-spreading algorithm of MC-2D-CDMA(Multi-Carrer 2-Dimension Code Division Multiple Access)uses a simple correlator and complex spread spectrum sequences.Each chip of spreading spectrum sequence is in two sub-carriers.With one sub-carrier in deep fading,the chip in the other sub-carrier would compensate to improve performance.Orthogonal restore correlation (ORC) explained the algorithm.The performance was examined analytically and by computer simulations.The performance is better than tha of regular MC-2D-CDMA model.

| Abstract: | The de-spreading algorithm of MC-2D-CDMA (Multi-Carrier 2-Dimension Code Division Multiple Access) uses a simple correlator and complex spread spectrum sequences. Each chip of spreading spectrum sequence is in two sub-carriers. With one sub-carrier in deep fading, the chip in the other sub-carrier would compensate to improve performance. Orthogonal restore correlation (ORC) explained the algorithm. The performance was examined analytically and by computer simulations. The performance is better than that of regular MC-2D-CDMA model. |
