摘要： A method of power control in a wireless communications system wherein blocks are transmitted from a transmitter to a receiver via a wireless transmission channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; determining if received blocks have been successfully decoded; identifying the received blocks as pass or fail blocks; when pass blocks are received, comparing the target signal quality value with the received signal quality value and decreasing the target value only if the target value is greater than the received signal quality value less a margin.

摘要： A method, apparatus and program. The method comprises: receiving a signal comprising a sequence of encoded symbols, each corresponding to one of a plurality of possible states; for each symbol in the sequence, determining a set of state metrics each representing a probability that the respective symbol corresponds to each of the plurality of states; and decoding the signal by processing runs of recursions, using runs of forward recursions and runs of reverse recursions. The decoding comprises performing a plurality of repeated iterations over the sequence, and for each iteration: dividing the sequence into a plurality of smaller windows, processing the windows using separate runs of recursions, and performing an associated warm-up run of recursions for each window. The decoding further comprises, for each repeated recursion: alternating the direction of the warm-up runs between forward and reverse with each successive iteration over the sequence, storing one of the sets of state metrics from each window, and initialising the warm-up run of each window using a corresponding stored set of state metrics from a previous iteration.
