Abstract
A system and method for reducing the interference experienced by sensitive electronic devices, such as hearing aids, operative in the vicinity of CDMA user communication devices. A transmitter of the communications device is configured to transmit signal power substantially continuously at a full rate power level irrespective of the variable data rate at which the transmitter would otherwise be operative. In a first embodiment, a variable rate vocoder within the transmitter is directed to perform full-rate vocoding, irrespective of an instantaneous level of user speech. In a second embodiment, a microprocessor builds full-rate frames using repeated versions of code symbols generated by the vocoder. In a third embodiment, the microprocessor builds full rate frames by generating signaling bits of a predetermined pattern to pad otherwise non-full frames.
