摘要： Various embodiments of the systems and methods described herein may be used to compute a minimum variance unbiased estimator by receiving a first OFDM signal at a pilot tone, receiving a second OFDM signal sent in the same frequency band and determining a differential phase metric between the first OFDM signal and the second OFDM signal. In some embodiments, the differential phase metric may be used to diversity combine synchronization statistics. In various embodiments, the differential phase metric may be used to detect a narrow-band interference.

摘要： A transmitter includes a coupler (318) to measure output power. The output power is compared to a set value and a threshold. If the power is above the threshold, the gain of an output amplifier (316) is adjusted toward the set value. If the power is below the threshold, an extrapolation of the linear portion is used to obtain the set power level.

摘要： The present invention provides systems and methods are provided to allow a network device to simultaneously monitor multiple adjacent wireless physical layer channels. If network communications are discovered on an adjacent channel, the network device may move to this adjacent channel. Accordingly, the network device is able to discover other devices or services existing on the adjacent channel, and is able to avoid interference caused by adjacent channels coexisting on the same frequency bands. After moving to the adjacent channel, a standard MAC protocol is able to regulate channel excess amongst all the network devices coexisting on the new channel.
摘要翻译：本发明提供的系统和方法被提供以允许网络设备同时监视多个相邻的无线物理层信道。如果在相邻信道上发现网络通信，则网络设备可以移动到该相邻信道。因此，网络设备能够发现存在于相邻信道上的其他设备或服务，并且能够避免由相同频带上共存的相邻信道引起的干扰。在移动到相邻信道之后，标准MAC协议能够调节在新信道上共存的所有网络设备中的信道超量。
