A system includes a repeater and a data processor. The repeater is for relaying data between a base station and a handset. The repeater is configured to receive data from a plurality of cells in a network and relay at least a portion of the received data to a handset on a first channel. The data processor is coupled to the repeater. The data processor is configured to extract, from the received data, network information characterizing different channels in a network being utilized by neighbor cells. The data processor is configured to determine, from a set of supported channels that the repeater is capable of utilizing for relaying data and using the extracted network information, a set of monitor channels. The repeater is configured to monitor a channel characteristic of channels contained in the set of monitor channels. Related apparatus, systems, techniques and articles are also described.

Selecting relay frequencies in a mobile repeater

A repeater system for relaying wireless communications between a base station and one or more devices having: a repeater to relay network information from a base station to one or more devices; a donor antenna configured to receive and/or transmit network information between the repeater and the base station; a power supply external to the repeater; and, a server antenna integrated with the power supply, the server antenna configured to receive and/or transmit network information between the repeater and the one or more devices.

Integrated power supply and antenna for repeater

Methods and systems for providing reduced bandwidth acquisition latency may comprise communicating a reservation request for bandwidth allocation for devices operating under a wired network protocol, where the reservation request may be sent by wired network devices via a wireless network protocol over a wireless network. Bandwidth may be allocated in the wired network for the requesting devices by a network controller. Data may be communicated with the requesting devices via the wired network. The wired network communication protocol may comprise a multimedia over cable alliance (MoCA) standard. The wireless protocol may comprise an IEEE 802.11x standard, a Bluetooth standard, and/or any non-public network protocol. The communication of the reservation request via the wireless protocol may decrease a latency of the wired network. A medium access plan (MAP) may be generated by the network controller based on the reservation request and may comprise a bandwidth allocation for the requesting devices.

Channel-sensitive power control

An antenna system includes a donor antenna sub-system, a server antenna sub-system, and a processor to optimize the gain of the repeater in the system. The gain in the antenna system is increased by optimizing the isolation between the donor and/or server antenna sub-systems according to a cost function.

System for maximizing gain in a repeater

A communication receiver which applies signal processing for quantitatively estimating receive signal factors such as communication channel quality, signal characteristics, and overall system received bit error rate (BER) or packet error rate (PER) and which applies a general algorithm for mapping these estimated factors to control receiver performance and minimize power consumption.

An accurate channel frequency response is obtained by processing an extracted number of pilot tones provided at different locations within a received OFDM symbol. This includes filtering the extracted pilot tones with a first window function, converting the thus filtered pilot tones to a first channel impulse response signal that may include a main tap and a plurality of adjacent taps, removing taps whose absolute values or energy levels are below a predetermined level, processing the remaining taps having sufficient absolute values or energy levels into a second channel impulse response signal that is significantly free of noises, converting the second channel impulse response signal to a frequency-domain signal, and filtering the frequency-domain signal with a second window function having an inverse characteristic of that of the first window function to obtain an accurate channel frequency response.

Channel estimation in a pilot assisted OFDM system

A circuit for self-calibrating a gain control system samples the output of a digital amplifier coupled in series with one or more analog amplifiers to correct errors in a discrete stepped gain control. A digital gain control circuit controls both the digital amplifier and at least one analog amplifier to produce a smooth linear and continuous gain, wherein perturbations in the digital control of gain are smoothed by a signal applied to gain control circuit by a gain step correction circuit.

A diversity receiver includes a first RF front end module for receiving a first RF signal, and frequency converting the first RF signal and outputting a first diversity signal, a second RF front end module for receiving a second RF signal, frequency converting the second RF signal and outputting a second diversity signal, a first converter for converting the first diversity signal to a first time-domain signal, a second converter for converting the second diversity signal to a second time-domain signal, a first transformer for translating the first time-domain signal to a first frequency-domain signal, a second transformer for translating the second time-domain signal to a second frequency-domain signal, a first pre-equalizer for equalizing the first frequency-domain signal, a second pre-equalizer for equalizing the second frequency-domain signal, and a combiner for combining the first and second pre-equalized frequency-domain signals. The diversity receiver further includes a channel estimator having a mirror window.
