Abstract: In a communication system in which direct sequence spread spectrum modulation techniques are used, interference is generated in communication by remote stations since the communication share the same frequency spectrum. In order to increase system capacity the power level of the remote station transmitters are controlled by the local station. A setpoint in generated at the local station by a power control processor (118) and compared by a comparator (120) with the remote station signal strength measured at the local station by a power averager (114). The result of this comparison is used to generate power level adjustment commands by a command generator (122) which are transmitted to the remote station. The remote station is responsive to the power level adjustment commands for increasing or decreasing remote station transmitter power. In a spread spectrum communication system in which data is encoded at variable data rates, the local station determines via a rate determination processor (116) the rate at which received data was encoded by the transmitting remote station. The data is decoded by decoder (112) at each possible rate with error metrics generated that are representative of the quality of the data decoded at each rate. A rate decision algorithm is used by processor (116;) to evaluate the error metrics and make a decision on the rate at which the data was transmitted. A pattern match of rate decisions is used by processor (118) to modify a setpoint so as to closely control the transmitting power of the remote station as a function of the quality of the received data.

Abstract: FIELD: digital communication systems. SUBSTANCE: for controlling power of communication system using direct sequential modulation method with spectrum stretching where remote stations cause noise due to use of same frequency spectrum, power level of distant- station transmitters is controlled by local station. The latter shapes desired value and compares it with remote- station signal strength measured at local station. Result of comparison is used to shape power level control commands which are transmitted to remote station. In response to power-level control commands, remote station increases or decreases power of its transmitter. Stretched-spectrum systems where data are encoded at varying data transmission speeds, have their local stations determining speed at which data received were encoded by remote sending station. Data are decoded at every possible speed and error certificates are shaped to characterize data decoded at every speed. Error certificates are estimated using speed calculation algorithm. Configurations of speed solutions are matched for changing desired value so as to ensure accurate transmission power control of remote station as function of characteristics of data received. EFFECT: improved rated power of system. 22 cl, 5 dwga
