| Abstract: | A novel de-spread re-spread smart antenna with equalizers is proposed. By using a reference signal equalizer and time domain equalizer, the antenna array is mainly used to cancel the multi-user interference while the time domain equalizer is mainly used to cancel the multi-path interference. The expected user signal for training the antenna array and the equalizers is generated by re-spreading the demodulated expected user data. Simulation results show that the performance of the proposed smart antenna is better than that of the traditional de-spread re-spread smart antennas. |
