    Abstract: A SPREAD-SPECTRUM SYSTEM AND METHOD FOR PROVIDING HIGH-CAPACITY COMMUNICATIONS THROUGH MULTIPATH COMPENSATION.A MULTIPATH PROCESSOR INCLUDING A FIRST PLURALITY OF CORRELATORS, A SECOND PLURALITY OF CORRELATORS, A FIRST ADDER, A SECOND ADDER, AND A SELECTRO DEVICE OR A COMBINER DEVICE IS PROVIDED FOR TRACKING A SPREAD -SPECTRUM SIGNAL ARRIVING IN IS PLURALITY OF GROUPS.THE FIRST PLURALITY OF CORRELATORS DESPREADS A FIRST GROUP OF SPREAD-SPECTRUM SIGNALS AS A FIRST GROUP OF DESPREAD SIGNALS WHICH ARE ADDED BY THE FIRST ADDER TO GENERATE A FIRST COMBINED-DESPREAS SIGNAL.THE SECOND PLURALITY OF CORRELATORS DESPREADS A SECOND GROUP OF SPREAD-SPECTRUL SIGNALS AS A SECOND GROUP OF DESPREAD SIGNALS WHICH ARE ADDED BY THE SECOND ADDER TO GENERATE A SECOND COMBINED- DESPREAD SIGNAL.THE SELECTOR DEVICE SELECTS EITHER THE FIRST OR THE SECOND COMBINED-DESPREAD SIGNAL AND OUTPUTS THE SELECTED SIGNAL.ALTERNATIVELY,THE COMBINER DEVICE COMBINES THE FIRST AND THE SECOND COMBINES-DESPREAD SIGNALS AND OUTPUTS THE COMBINED SIGNAL.

    Abstract: The present invention discloses a communication station for communicating with a second station in a cellular-communication network using spread spectrum modulation wherein the second station transmits power commands to the communication station based on a received power level from the communication station, the communication station comprising: a transmitter having an adjustable transmitter power level for transmitting spread-spectrum signals; means for sequentially receiving power commands from a second station with which communication is being conducted; means for comparing a sequence of at least two of the received power commands to determine if the received commands in the sequence match; and means for adjusting the transmitter power level at a same rate as the reception of the power commands; wherein if the command sequence matches the transmitter power level is adjusted by a different amount than if the command sequence does not match. A method for adjusting a transmitter power level is also disclosed.
