    Abstract: A mobile subscriber unit (102) transmits a signal including vocoder voices frames to a base unit (104) within a communication system (100). The base unit (104) repeats the signal including error information from the voice frames to one or more final recipient unit(s). The originating subscriber unit (102) listens to these error mitigated repeated frames and compares the received signal having error information to voice frame conditions, such as calculated, delayed and muted signal patterns. Based on the comparison, the subscriber unit (102) adjusts its power accordingly.

    Abstract translation: 移动用户单元(102)将包括声码器语音帧的信号发送到通信系统(100)内的基本单元(104)。 基本单元(104)将包括从语音帧的错误信息的信号重复到一个或多个最终接收者单元。 始发用户单元(102)监听这些错误减轻的重复帧,并将具有错误信息的接收信号与诸如计算的,延迟的和静音的信号模式之类的语音帧条件进行比较。 基于比较,用户单元(102)相应地调整其功率。

    Abstract: A decoder circuit is provided which employs digital sampling and correlation apparatus to detect the presence of a received tone signal exhibiting a predetermined frequency. Samples of received tone signals are taken and, in effect, multiplied by a substantially rectangular observation window which includes a bite interval of selected duration and location therein. A correlator correlates the windowed samples to detect samples corresponding to the predetermined frequency (main lobe frequency). A significant decrease in undesired side lobe response is thus achieved.

    Abstract: A received synchronization pattern is compared against first and second know n synchronization patterns. If the received pattern is substantially similar t o the first known pattern, the payload is processed as voice; and if the received pattern is substantially similar to the second known pattern, the payload is processed as non-voice. Alternatively, a target synchronization pattern dependent on an operating mode is selected. The received pattern is compared against the target pattern. If the received pattern is substantiall y similar to the target pattern, the payload is processed; otherwise, the burs t is discarded. In yet another alternative, the received pattern is compared against first and second known synchronization patterns having a common length. If the received pattern is substantially similar to the first known pattern, a first operating mode is selected, and if the received pattern is substantially similar to the second known pattern, a second operating mode i s selected.
