Patent number: 8654885Abstract: An embodiment of the present invention includes a technique to calibrate receiver and transmitter in a communication system. N digitized samples I(n) and Q(n) are stored. The N digitized samples represent in-phase and quadrature (I-Q) components, respectively, of a down-converted signal from a receiver. The I-Q components are generated from a quadrature demodulator or modulator having I-Q imbalance. Phase and gain adjustment constants are computed from the N digitized samples to compensate for the I-Q imbalance using a closed form solution. Another embodiment of the present invention includes a technique to calibrate a transceiver in a communication system without using a calibrated reference receiver. A first test signal at a first frequency is injected to a transmitter having a quadrature modulator with I-Q imbalance. The quadrature modulator has a carrier frequency. The transmitter generates a transmitter signal.Type: GrantFiled: June 5, 2007Date of Patent: February 18, 2014Assignee: QUALCOMM IncorporatedInventors: Chaekwan Lee, Peter A. Thompson, Bill Xenakis, Kyung Sup Han

Publication number: 20090310691Abstract: Methods and apparatus for determining an accurate fractional carrier frequency offset (CFO) adjustment in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) system in an effort to properly compensate for the actual CFO between a transmitter and a receiver are provided. This enhanced fractional CFO adjustment may be based on a history of estimated fractional CFOs and estimated carrier-to-interference-plus-noise ratios (CINRs) and may be statistically derived from this history, therefore leading to a more accurate fractional CFO adjustment when compared to conventional fractional CFO estimations. A more accurate fractional CFO adjustment may lead to increased physical layer performance and decreased decoding errors (i.e., lower bit error ratio, or BER).Type: ApplicationFiled: June 12, 2008Publication date: December 17, 2009Applicant: QUALCOMM IncorporatedInventors: Jong Ro Park, Kyung Sup Han, Tae Ryun Chang
