Abstract:
Tandem-free vocoder operations (TFO) between non-compatible communication systems may be enabled through hardware modifications at communication elements within each system. In one aspect, each infrastructure entity in System 1 comprises an intra-system TFO Frame Generator G1, an intra-system TFO Frame Extractor E1, and a TFO Frame Extractor E2 of System 2, which is non-compatible to System 1. Each infrastructure entity in System 2 comprises an intra-system TFO Frame Generator G2, an intra-system TFO Frame Extractor E2, and a TFO Frame Extractor E1 of System 1.
