"Processes of transmission of a signal digitized by a radio channel.The establishment of voice communication through a radio channel in a wireless communication system and receiving a digitized speech signal transmitted in a full rate through D.And a radio channel in a wireless communication system, and encoder and a receiver in a transmitter for improved transmission of communication signals through a wireless channel.An encoder includes an encoder for improved half rate receiving a speech signal and generating a digital bit stream compressed into half rate and a signal expander receiving runNTE bits and generating a compressed bit stream is expanded into full rate for transmission through a radio channel.A receiver receives the communication signal enhanced transmitted.Which is selected from the group consisting of (a) a speech signal digitized encoded in full rate conventional and (b) a speech signal digitized encoded in half rate.Including the bit stream is expanded.The receiver includes an equalizer for enhanced full rate.An equalizer of half rate and a key initially routing the speech signal digitized received the full rate equalizer.In the full rate equalizer demodula the speech signal digitized received.Producing a signal demodulado of full rate and temporary information corresponding to the signal dibits of demodulado of full rate.An analyzer analyzes the dibits of temporary information and controls the key to route the speech signal digitized received to one of the equalizers for full rate and half rate.Based on the analysis.
