METHOD OF RECONFIGURATION OF RADIO PARAMETERS BASED ON COMMUNICATION CHANNEL MONITORING

摘要

The invention monitors a communication channel and estimates its characteristics from time to time, thus providing a dynamic estimate of channel characteristics. Based on the channel characteristics, a control processor calculates a preferred configuration of digital (and optionally, analog) signal processing to best manage the available energy for the present channel characteristics. The selected configuration is then down-loaded into communication modules stored in extra memory during runtime. The communication modules preferably include a one or more of: a reconfigurable forward error correcting codec (with adjustable code lengths and a plurality of code choices); a reconfigurable interleaver with adjustable depth; a decision feedback equalizer (DFE) with a reconfigurable number of taps; maximum likelihood sequence estimator with an adjustable number of states; a frequency hopping coder with an adjustable number of hops or hop rate; and a direct-sequence (or direct sequence spread spectrum) codec with an adjustable number of chips per bit.
