Abstract: The method includes receiving a signal comprising a received frame, the received frame having a plurality of received symbols and having a received information portion and a received frame quality indicator; storing at least one of the plurality of received symbols in a memory; demodulating the received information portion to form a demodulated information portion and demodulating the received frame quality indicator to form a demodulated frame quality indicator, the demodulated information portion and the demodulated frame quality indicator comprising a demodulated frame; re-encoding at least a portion of the demodulated frame to form an encoded frame, the encoded frame having a plurality of encoded symbols; comparing one of the plurality of encoded symbols with the at least one of the plurality of received symbols stored in the memory; and based on the comparison, estimating the channel parameter.

Abstract: The method includes acquiring a signal (501); inputting (502), at a first time, a received symbol to a demodulator having a plurality of outputs to produce a set of early outputs; inputting (504), at a second time, the received symbol to the demodulator to produce a set of on-time outputs; inputting (505), at a third time, the received symbol to the demodulator to produce a set of late outputs; and comparing (506) at least one output in the set of early outputs with at least one output in the set of late outputs to produce a timing measure.

Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.
