摘要： The mobile telephone (100) is provided with the capability for automatically adjusting the gain of a microphone (102) of the telephone (100) based upon the detected noise level in which the cellular telephone (100) is operated. As the noise level increases, the gain of the microphone (102) is automatically decreased, thereby compensating for the natural tendency of telephone (100) users to speak more loudly in noisy environments. In the exemplary embodiment, the cellular telephone (100) includes a digital signal processor (110) configured or programmed to apply the detected noise level to look-up tables (116, 118) relating various noise levels to appropriate speaker (104) and microphone (102) gain levels. Also, in the exemplary embodiment, the mobile telephone (100) includes a speaker (104) and the gain of the speaker (104) is adjusted to incrase in response to an increase in the background noise level. A method of automatically adjusting the gain of speaker (104) in a wireless communications device (100) includes the steps of obtaining a digital value representing the available headroom, estimating the background noise level, and adjusting the volume based on the background noise estimate and the available headroom. Thus, for example, the need for manual volume control buttons on a cellular telephone (100) is eliminated.

摘要： In one embodiment, a mobile station (150) such as a dual-mode, AMPS and CDMA, handset communicates with an AMPS base station (102)in a wireless communication system (100). The mobile station (150) includes an acoustic echo canceller (124), which can detect acoustic echo, for example, feedback from the handset speaker (126)to the handset microphone (128), during communication between themobile station (150) and the base station (102), and cancel or eliminate the acoustic echo. The mobile station (150) also includes a network echo suppressor (116) coupled to the acoustic echo canceller (124). For example, the network echo suppressor (116) can read a parameter (133) set by the acoustic echo canceller (124). The network echo suppressor (116) attenuates or mutes a network echo caused by portions of the communication returning to the mobile station (150) from the base station (102) after a network propagation delay. Coupling the network echo suppressor (116) to the acoustic echo canceller (124) ensures proper interaction between the network echo suppressor (116) and acoustic echo canceller (124).

摘要： The present invention is a novel and improved method and appartus for performing multiple applications on a microprocessor or DSP. One embodiment of the invention includes a car kit for interfacing with a cellular telephone. The car kit includes a digital signal processor for performing digital signal processing and a cradle unit for holding the cellular telephone and for providing a link to said digital signal processor. Additionally, an on-chip memory is provided, located on an integrated circuit with the digital signal processor, for storing a limited function program that control said DSP. Off-chip memory stores multiple limited function programs and for laoding any one of the limited function programs to the on-chip memory.
