Abstract: Technologies are generally described for modifying sound output in a personal communication device. Example devices described herein may include one or more of a communication unit, an audio processor, and/or a sound leakage detector. A communication signal may be received from the other party during personal communication by the communication unit. The communication signal may be converted by the audio processor into receiver sound for output by a receiver speaker. The sound leakage detector may provide a sound leakage indication if the sound leakage detector receives an input indicating a leakage of the receiver sound being output by the receiver speaker. Further, the audio processor may modify the receiver sound based on the sound leakage indication.

Abstract: Compression of an input signal prior to high power radio frequency (RF) amplification and transmission is disclosed. A compression device can receive an input signal and generate a compressed signal that can be passed to an amplification stage to reduce intermodulation effects. The compression device can further generate compression information that can be transmitted to enable a mobile device receiving an amplified version of the compressed signal and the compression information to decompress the amplified version of the compressed signal. Further, a mobile device that can receive an amplified compressed signal and compression information, such that the mobile device can decompress the amplified compressed signal, is also disclosed. The disclosed subject matter can enable use of lower cost, smaller, and less complex RF amplifiers within a wireless network environment.
