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: Various embodiments provide for waveguide assemblies which may be utilized in wireless communication systems. Various embodiments may allow for waveguide assemblies to be assembled using tools and methodologies that are simpler than the conventional alternatives. Some embodiments provide for a waveguide assembly that comprises a straight tubular portion configured to be shortened, using simple techniques and tools, in order to fit into a waveguide assembly. For instance, for some embodiments, the waveguide assembly may be configured such that the straight portion can be shortened, at a cross section of the portion, using a basic cutting tool, such a hacksaw. In some embodiments, the straight portion may be further configured such that regardless of whether the straight tubular portion is shortened, the waveguide assembly remains capable of coupling to flanges, which facilitate coupling the straight tubular portion to connectable assemblies, such as other waveguide assemblies, radio equipment, or antennas.

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: 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.
