Hi Glen, I'll give you two of my reasons: 1. trellis encoding -> higher order modulation 2. for OFDMA with multiple carriers (not FSK of course), where you still need to fit inside the channel spacing allocation. Spectrum is not cheap :) Cheers, Adrian ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
