ADAPTIVE POWER CONTROL FOR A SPREAD SPECTRUM TRANSMITTER |
摘要 |
<p>The present invention is directed to a mobile station for performing adaptive-power control of a spread-spectrum transmitter of the mobile station operating in a cellular-communications network using spread-spectrum modulation, wherein a base station transmits a first spread spectrum channel and a second spread-spectrum channel different than the first spread spectrum channel, each mobile station comprising: means for acquiring and decoding the first spread spectrum channel; means for detecting a received power level of the first spread spectrum channel; means for detecting a received power level of the first spread spectrum channel; means for decoding a word of the second spread spectrum channel as a word value; means for generating a comparison signal by comparing the received power level to said word value; means for transmitting a transmitter spread-spectrum signal; an antenna; and variable-gain means responsive to said comparison signal for adjusting a transmitter-power level of the transmitter spread-spectrum signal from said transmitter.</p> |
