Abstract: A method of calibrating multiple types of base stations is provided. The method includes selecting one of a plurality of technology types for the wireless base station. The wireless base station has an adaptive antenna array. A calibration is performed for the wireless base station based on the selected technology type.

Abstract: A method for providing digital compensation and vector calibration for a base station in a wireless network is provided. The method includes performing a single process that is operable to provide simultaneously both digital compensation and vector calibration for the base station. According to one embodiment of the present disclosure, the single process is performed by receiving a transmitted signal based on a compensation/calibration (C/C) signal, processing the received signal, generating a C/C weight based on the processed signal, and using the C/C weight in a normal operational mode for the base station.

Abstract: An apparatus for reducing the crest factor of a multi-carrier transmission system. The apparatus comprises a plurality of single carrier crest factor reduction circuits. Each of the single carrier crest factor reduction circuits receives a selected one of a plurality of single carrier signals and generates a crest factor reduced (CFR) single carrier signal. The apparatus also comprises an up-converter for up-converting each of the CFR single carrier signals to a selected frequency and combining the up-converted CFR single carrier signals to thereby produce a multi-carrier signal. The apparatus further comprises a first multi-carrier crest factor reduction circuit for receiving the multi-carrier signal and generating a first crest factor reduced (CFR) multi-carrier signal.

Abstract: An apparatus is provided for reducing the peak-to-average power ratio (PAPR) of a multicarrier transmission system. The apparatus comprises a detector for receiving a plurality of symbols to be transmitted and determining a peak amplitude of the plurality of symbols and a controller for determining if the peak amplitude associated with the plurality of symbols exceeds a predetermined threshold. If the peak amplitude exceeds the predetermined threshold, the apparatus generates at least one correction carrier signal. The at least one correction carrier signal is combined with a plurality of modulated carrier signals associated with the plurality of symbols to thereby reduce a peak-to-average power ratio associated with the plurality of modulated carrier signals.
