| Abstract(in English) | Adaptive multi-code transmission proposed as technique to improve performance of transmission rate for wireless LAN. This paper deals with the scheme to improve the throughput performance of adaptive multi-code transmission technique in a frequency selective fading channel. Conventional system has a demerit that cross-correlation between the spreading codes increases by the delay wave. In order to improve the throughput performance, this paper proposes adaptive multi-code transmission technique using orthogonal spreading code without synchronization which can keep orthogonality against the delay waves. In order to estimate more optimum bit error rate in above channel, this paper also proposes adaptive multi-code transmission technique using the link quality estimation by pseudo bit error rate which has potential for simplified processing. The simulation results show that proposed method enhances throughput performance in comparison with conventional one in a frequency selective fading channel. |
