| Abstract(in English) | Use of frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can significantly improve the bit error rate (BER) performances of DS-CDMA downlink in a frequency-selective fading channel. However, the uplink BER performance degrades due to a strong multi-user interference (MUI). Recently, we proposed a single-carrier spread spectrum multiple access (SC-SSMA), which uses frequency-domain interleaving and MMSE-FDE to improve the uplink BER performance. However, in a multi-cell environment, the uplink capacity of SC-SSMA may degrade due to an inter-cell interference. In this paper, we evaluate, by computer simulation, the uplink capacity of SC-SSMA in a multi-cell environment. |
