摘要： 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.

摘要： Systems and methods for transceiver communication are discussed herein. A filter module may be configured to filter each carrier signal of a multicarrier transmit signal with a different bandpass filter, each bandpass filter configured to filter a different frequency band. A carrier control module may be configured to control the plurality of bandpass filters of the filter module using a carrier selection signal to enable or disable each bandpass filter, thereby coupling carrier signals of the multicarrier transmit signal to a first set of bandpass filters and decoupling a second set of bandpass filters. Filtering the carrier signals of the multicarrier transmit signal is performed by the first set of bandpass filters while the decoupling of the second set of bandpass filters limits energy in the respective frequency band. An antenna may be configured to transmit the filtered multicarrier transmit signal.

摘要： Systems and methods for combining signals from multiple active wireless transmitters are discussed herein. An exemplary system comprises a radio enclosure, a first transmitting RFU, a second transmitting RFU, and a combiner. The first transmitting RFU may be configured to receive a signal, upconvert the signal, compare a phase of the upconverted signal to a predetermined phase value, and adjust the phase of the signal based on the comparison to provide a first phase-adjusted upconverted signal. The second transmitting RFU may be configured to receive the signal, upconvert the signal, compare a phase of the upconverted signal to the predetermined phase value, and adjust the phase of the signal based on the comparison to provide a second phase-adjusted upconverted signal. The coupler may be configured to combine the first and second phase-adjusted upconverted signals to create an output signal and provide the output signal to an antenna for transmission.
