Abstract: A carrier tracking circuit includes a first phase adjustment circuit coupled to an input of a delay element and a second phase adjustment circuit coupled to an output of the delay element. A phase correction circuit is coupled to output of the delay element is operable to generate a phase adjustment value based upon a data symbol output from the delay element. The phase correction circuit includes a double phase correction circuit to prevent double application of the same phase adjustment value to a symbol by both the first and second phase adjustment circuits. The carrier tracking circuit may be used in OFDM communications systems with each data symbol being an OFDM symbol and with the delay element being an FFT. The carrier tracker circuit also may include a feed forward circuit for correcting the phase error of a given data symbol using a phase error generated from that symbol.

Abstract: A 10 MHz channelized orthogonal frequency division multiplexing (OFDM) transmitter is provided that communicates using a modified OFDM packet structure with a half-rate oscillator having standard accuracy. The transmitter has an inverse fast fourier transform (IFFT) data processor that appends an outer pair of data subcarriers on either end of an OFDM subcarrier profile. An IFFT long sync processor appends an outer pair of binary phase shift key (BPSK) subcarriers on either end of an OFDM long sync subcarrier profile. By copying or appending the information of the data subcarriers closest to zero Hz. to more robust locations, 10 MHz channelized OFDM can be achieved with half-rate clocks and 20 PPM oscillators.

Abstract: An on-signal calibration system I and Q signals of a transmitter to remove distortions in the RF output signal. The transmitter generates I and Q values and converts, modulates and combines the I and Q values into the RF output signal for transmission. The calibration system includes a detector, a sampler, a selector, an imbalance estimator, and an IQ corrector. The detector senses the RF output signal and provides a detection signal indicative thereof. The sampler samples the detection signal and provides digital samples. The selector selects from among the digital samples that correspond to predetermined ranges of the I and Q values, or otherwise predetermined selection boxes at predetermined phases. The imbalance estimator determines at least one imbalance estimate based on selected digital samples. The IQ corrector corrects the I and Q values using at least one imbalance estimate.
