Abstract: A frame error correction circuit may identify and correct errors in data frames provided to a receiver as part of a diversity communications scheme. The frame error correction circuit may further align the data frames so that the data frames can be compared. The frame error correction circuit may perform a bit-wise comparison of the data frames and identify inconsistent bit positions where bits in the data frames differ from one another. Once inconsistent bit positions have been identified, the frame error correction circuit may access a permutation table of permutations of bits at the inconsistent bit positions. In some implementations, the frame error correction circuit uses the permutation table to reassemble permutations of the data frames. In various implementations, the frame error correction circuit performs a CRC of each permutation of the data frames, and provides a valid permutation to a network.

Abstract: According to some embodiments, a master device sends synchronization packets to one or more slave devices, and does so periodically based on a master clock signal having a master clock frequency. At each of the slave devices, an algorithm estimates the master clock frequency based on the timing of synchronization packet arrivals the slave device. The algorithm may estimate the master clock frequency using both the currently-observed timing of synchronization packet arrivals and the history of previous synchronization packet arrivals (e.g., previously-observed timing of synchronization packet arrivals). Based on the estimated master clock frequency, each of the one or more slave devices can update the frequency of their respective slave clock signal (e.g., using a frequency offset) to match that of the estimated master clock frequency.

Abstract: In some embodiments, a first RF signal is received at a wireless repeater, a signal quality is determined based on the first RF signal, the signal quality is analyzed based on a parameter, an operation mode is auto selected based on analysis of the signal quality, and a second RF signal based on the first RF signal is generated for transmission according to the selected operation mode. Under one mode, a first RAC of the wireless may generate data based on a first IF signal downconverted from a first RF signal. Based on the data, a second RAC of the wireless repeater may generate a second IF signal, which can be used to generate a second RF signal for transmission. Under another mode, the first RAC may provide the IF signal to the second RAC, which provides the IF signal for generation of the second RF signal.

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.
