摘要
The technique of redundantly retransmitting digitized voice data on multiple sequential frequencies increases the channel bit rate above the minimum required for normal communication in a frequency- hopping communication system for digitized voice signals. Digitized voice data is redundantly retransmitted on multiple sequential frequencies and the channel bit rate is increased above the minimum required for normal communication. Repeated transmissions of the same block of digitized voice data occurs n times at n times the bit rate of the original digitized voice data. A frequency-hopping transmitter transmits on different channels, or carrier frequencies, which are modulated by the digitized voice data signals from a transmitter data buffer. A receiver data buffer holds n blocks of digitized voice data. A signal quality estimator estimates which of the n blocks of digitized voice data has a desirable signal quality and selects the block of digitized voice data having the desirable signal quality at an output terminal of the system.
