Сущность данного способа регулировани мощности излучени передатчика состоит в измерении дисперсии ошибки оценивани коэффициента передачи пр мого канала. Результаты этих измерений передают по каналу обратной св зи. Затем определ ют среднеквадратическое значение ошибки оценивани коэффициента передачи пр мого канала. Далее вычисл ют текущее значение мощности передатчика и устанавливают величину этой мощности. 1 ил.The invention relates to radio engineering. The purpose of the invention is to improve the noise immunity of communication. The essence of this method of regulating the transmitter radiation power is to measure the variance of the error of estimating the forward channel transmission coefficient. The results of these measurements are transmitted through the feedback channel. Then, the root mean square error of the estimation of the transmission coefficient of the forward channel is determined.
