1 /*
2 * This program exercises our ThemWi implementation of TFO transform for
3 * GSM-HR. It reads a stream of radio leg A Rx frames from a TW-TS-005 Annex B
4 * hex file and writes the "pristine" stream intended for radio leg B Tx
5 * into another TW-TS-005 Annex B hex file. DTXd can be enabled or disabled;
6 * the output can be in either TS 101 318 or RFC 5993 format.
