摘要： Methods and systems for multi-path video and network channels may comprise a communication device comprising a wideband path (WB) and a narrowband path (NB), wherein the WB may be operable to receive a plurality of channels and the NB may be operable to receive a single channel. Video channels and a network channel may be received in the WB when the device is operating in a first stage. Video channels and a network channel may be received in the WB and the network channel may also be received in the NB when the device is operating in a second stage. The network channel may be received in the NB when the device is operating in a third stage. The reception of the network channel from both the WB and the NB may enable a continuous reception of the network channel in a transition between the first and third stages.

摘要： A method and system for combining a guard interval and a corresponding portion of a received symbol, whereby when receiving a signal that contains the symbol with a guard interval corresponding to the symbol, a portion of the guard interval that is free from inter-symbol interference may be extracted, and the extracted portion of the guard interval may be combined with the corresponding portion of the symbol. The extracting and combining may be done after a determining, based on a delay profile provided by the received signal, that a delay spread is smaller than a predetermined channel delay. The delay spread may be determined by filtering an instantaneous delay spread associated with the received signal. The filtering may be performed using a 1-tap infinite impulse response low-pass filter. The low-pass filter may include a time constant that is the inverse of a maximum Doppler frequency shift.

摘要： Systems and methods for adjusting timing in a communication system, such as an OFDM system are described. In one implementation an error signal is generated to adjust the timing of a variable rate interpolator so as to adjust FFT timing. The error signal may be based on detection of significant peaks in an estimate of the impulse response of the channel, with the peak locations being tracked over subsequent symbols and the system timing adjusted in response to changes in the peaks.

摘要： An implementation of a signaling protocol for low power and large scale wireless networks provides a media access control (MAC) that produces a low rate two-way communication link between a commercial infrastructure and a very large number of small, low-cost devices known as electronic tags. The numerous tags attached to merchandise or shelves communicate with a number of access points (AP) distributed throughout a facility containing merchandise for sale or storage. A store controller maintains the pricing database for the point of sale (POS) registers of the facility. Price changes are transmitted in real time to the tag, thus updating the merchandise tags and the point of sales (POS) registers simultaneously. The tags contain a controller and a battery in which conservation of power is crucial to the life of the tags.
