"Recent simulator studies have concluded that significant channel interference and fallout occurwhen interferors occur within the uplink transmission band. Although methods involvingredundancy, encryption, compression, code/decode (CODEC) can address improvements insensitivity, each is also susceptible to interference in the RF link domain. What is proposed hereis an entirely new method of implementing Forward Error Correction (FEC) which uses a featurescale forecast model. It is anticipated that this method will decrease, by an order-of-magnitude,propagation errors due to the Bit Error Rate (BER) in the RF link domain. As more and more wireless devices take advantage of connectivity in the RF domain,susceptibility to the bit error rate (BER) will remain an issue. This problem will remain fordevices in the digital domain, as well as in the analog domain. Digital devices include otherdigital sonobuoys and other digital in-situ sensors, digital telephones and digital assistants, suchas the Personal Digital Assistant (PDA). Each of these devices communicates wirelessly usingvarious message and packet structures, each of which could benefit by a forecast method for aForward Error Correction (FEC) method. Research into the optimum method of implementingFEC for each of the various message and data domains will have to be conducted. In certaincases, it may be necessary to implement unique algorithms for the most efficiency, whereas m
