Actually, there's some question as to the utility of FEC for MBC systems. Since trail dissipation is a rapid exponential process, signals tend to fall below threshold, on average, in the middle of packets; the required overhead to correct half a packet is quite large, and since one could potentially use those overhead bits to send real information, you're much better off with some sort of a selective retransmission system. -- -=Paul Flaherty, PhD | "The Enemy of the Good is the Better." ->paulf@Stanford.EDU (N9FZX) | -- Gen.

The task force would work with all of the FCC's bureaus and offices that are involved in PCS issues, and would be responsible ''for assuring consistency between policies and rules for narrow-band and wide-band PCS.'' FCC Chairman Reed Hundt said that ''I am confident that under the leadership of Ralph Haller, the PCS task force will lead the Commission in the timely development of a comprehensive regulatory framework for PCS.''
