Abstract: A code transmitted in a wireless format is to be detected. A power level associated with the code is determined. The determined power level is compared with a plurality of thresholds. A test statistic is increased or decreased based on which of the thresholds that the determined power level falls within. If the test statistic exceeds an acceptance threshold, the code is deemed acquired. If the test statistic is below a dismissal threshold, the code is deemed not present. If the test statistic does not exceed the acceptance threshold and the test statistic is not below the dismissal threshold, the testing for the code is repeated.

Abstract translation: 要检测以无线格式发送的代码。 确定与代码相关联的功率级别。 将确定的功率电平与多个阈值进行比较。 基于所确定的功率水平在哪个阈值内增加或减少测试统计量。 如果测试统计数据超过接受阈值，则代码被视为已获得。 如果测试统计数据低于解雇阈值，则代码被视为不存在。 如果测试统计量不超过接受阈值，并且测试统计量不低于解雇阈值，则重复对代码的测试。

Abstract: In a TDD wireless communication system between transmitters and associated receivers, automatic gain control of a receiver is only applied during the corresponding time slot within the TDD signal time frame architecture. Successive received signal strengths are measured and gain levels are stored as estimates for an initial gain level in future time slots of the TDD signal. Estimating techniques, such as averaging or trending of received signal strength over successive time slots, and averaging or trending of gain level settings, provide improved estimation of future initial gain levels.
