摘要： In a quadrature modulator which receives a pair of carrier signals having phases perpendicular to one another, and I and Q signals, and which outputs a modulating signal, a quadrature error based on a phase difference between the pair of carrier signals is detected. In a state that the signal levels of the I and Q signals are each made to be zero, a pair of dc voltages for causing that the modulating signal outputted from the quadrature modulator is made to be a predetermined reference level, are each added to the I and Q signals. In a state that pairs of dc voltages are each changed and sequentially added to the I and Q signals, plural combinations of pairs of dc voltages for causing that a signal level of the modulating signal is made to be the predetermined reference level, are retrieved, and the quadrature error is calculated from simultaneous equations in which respective values of the retrieved plural combinations of pairs of dc voltages, the signal level of the modulating signal, and a quadrature error of the carrier signals are variables.

摘要： A method for comparing bit field contents for bit fields comprising less than a full complement of the source is provided. The method includes creating a mask covering the bit field in the source, setting bit positions within the mask that are outside the bit field in the source to predetermined values, combining the source against the mask to form an intermediate result, and comparing bits in the intermediate result to provide a final result. Alternately, the method may form a mask, combining the bit field with a comparison value to form an intermediate value, and perform a combined function using the mask to select bits from the intermediate value, or fixed zero or one values, and comparing this result with zero.

摘要： An orthogonal frequency division multiplexing (OFDM) transmitter method, consistent with certain embodiments of the present invention arranges OFDM data symbols representing data bits for transmission in a packet. A prescribed pattern of OFDM data symbols are removed (212) and replaced (216) with pilot symbols. The packet is then transmitted (220) to an OFDM receiver that receives the packet (224) and determines a channel correction factor from the pilot pattern. The receiver then estimates a plurality of channel correction factors, one for each of the plurality of OFDM symbols representing data (228) and uses these correction factors to correct the OFDM symbols representing data (232). Arbitrary data are then inserted in place of the pilot symbols (236). The OFDM symbols representing data along with the arbitrary data are then decoded using an error correction decoder that corrects the errors induced by substitution of the pilot symbols for data symbols (240).
