Abstract: Rapid failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet transport channel standards. Thus, resilient wireless packet communications is provided using a hardware-assisted rapid transport channel failure detection algorithm and a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, this is provided in combination with their existing protocols, such as rapid spanning tree and link aggregation protocols, respectively.

Abstract: An exemplary system comprises a linearizer module, a first upconverter module, a power amplifier module, a signal sampler module, and a downconverter module. The linearizer module may be configured to receive a first intermediate frequency signal and to adjust the first intermediate frequency signal based on a reference signal and a signal based on a second intermediate frequency signal. The first upconverter module may be configured to receive and up-convert a signal based on the adjusted first intermediate frequency signal to a radio frequency signal. The power amplifier module may be configured to receive and amplify a power of a signal based on the radio frequency signal. The signal sampler module may be configured to sample a signal based on the amplified radio frequency signal. The downconverter module may be configured to receive and down-convert a signal based on the sampled radio frequency signal to the second intermediate frequency signal.

Abstract: An example system comprises a first antenna and a modem. The first antenna is configured to receive a signal from a transmitting radio frequency unit. The signal includes data and a known sequence. The modem is configured to retrieve the known sequence from the signal, transform the known sequence and the data into a frequency domain, calculate averages of groups of neighboring frequency points in the frequency domain to reduce the effect of nonlinear noise in the signal, the neighboring frequency points corresponding to the preamble in the frequency domain, compare the calculated averages to an expected frequency response in the frequency domain, determine a correction filter to apply to the data based on the comparison, apply the correction filter on the data in the frequency domain to create corrected data, transform the corrected data from the frequency domain to the time domain, and provide the data.

Abstract: According to various embodiments, systems and methods are provided for improving signal quality and signal reliability over wireless communication using polarization diversity. Some embodiments use polarization diversity on a wireless channel to address and compensate for fading conditions such as non-frequency selective fading (also referred to as power fading, attenuation fading, and flat fading) and frequency selective fading (also referred to as multipath fading and dispersive fading). For example, some embodiments utilize a horizontal signal and a vertical signal on the same wireless channel when wirelessly communicating data between a transmitter and a receiver to address a fading condition.

Abstract: A system may include a transmitting device. The transmitting device may include one or more terminals for receiving a data signal and a first clock signal. A first phase lock loop may lock a phase of an initial periodic signal with a phase of the first clock signal, the first phase lock loop including a divider to generate the initial periodic signal based on the first clock signal. A decimation module may sample the initial periodic signal at a decimated rate of a backplane clock, the backplane clock being asynchronous with a clock that generated the first clock signal. A transmitting data block interface may construct data blocks and provide the data blocks to a receiving device, each of one or more of the data blocks including a portion of the data signal and at least one sample of the initial periodic signal.
