- 論文の詳細を見る
In DS-CDMA mobile radio communications systems, transmit power control (TPC) is indispensable to regulate the variations in the received signal power produced by mnltipath fading. However, a practical TPC raises and lowers the mobile transmit power only at discrete time instants (the TPC rate is on the order of 12kHz) and by a finite step size of the order of 1dB. Therefore, TPC cannot completely compensate the received signal power variations and hence, the transmission performance degrades in a fast fading channel. The objective of this paper is to understand how TPC acts in a fast fading channel with antenna diversity reception and. Based on this understanding, to model the TPC operation.
