This correspondence presents an algorithm for compensation of I/Q imbalance for a direct-conversion packet-switched orthogonal frequency-division-multiplexing (OFDM) communications system, which accounts for transmitter I/Q imbalance, receiver I/Q imbalance, phase/frequency error, and dispersive multipath fading. The proposed estimation algorithm is then(More)
A direct conversion 4.9 GHz to 5.925 GHz OFDM receiver IC with non-integer matched quadrature LO that supports channel bandwidths from 1 MHz to 28 MHz is manufactured on Jazz 0.35 mum BiCMOS process. This chip has a noise figure less than 6 dB and Input P1 dB of greater than -14 dBm at maximum gain. The I/Q gain mismatch is less than 0.15 dB and phase error(More)
The present study was designed to investigate the effects of reference microphone location on probe tube microphone measures of hearing aid response. The reference microphone of a clinical probe tube microphone system was located either at a position on the cheek (position A) or in close proximity to the microphone of an ear level hearing aid (position B).(More)
