摘要： A hybrid polar I-Q transmitter comprises an I-Q quantization circuit configured to receive an in-phase signal and a quadrature signal forming a first I-Q data pair, and generate a quantized in-phase signal and a quantized quadrature signal forming a second I-Q data pair, respectively, based on a resolution information of a digital-to-analog converter (DAC). Each of the first and second I-Q data pairs corresponds to a point in an I-Q constellation diagram comprising an I axis and a Q axis that are orthogonal to one another. The transmitter further comprises a quantization reduction circuit configured to determine a first rotation angle and a second rotation angle of the I-axis and Q-axis, respectively, based on the first I-Q data pair and the second I-Q data pair, and use the determined first rotation angle and the second rotation angle for generating an RF output signal.

摘要： An illustrative adaptive radio communications system comprises a cluster of waveform and application processor entities coupled and a plurality of transceivers. The transceivers convert radio frequency (RF) signals into digital in-phase and quadrature (I/Q) data, which is sent to the waveform processor entities via a network fabric. The waveform processor entities perform low-level waveform processing and the application processor entities perform high-level, distributed signal processing.

摘要： In a receiver circuit, an analog signal processor frequency-converts an input high frequency signal into a baseband signal, and performs low pass filtering at a cutoff frequency below a desired-wave band. An ADC converts an output of the analog signal processor into a digital signal. A digital signal processor compensates an output of the ADC for a signal component in the desired-wave band which has been attenuated by the filtering operation of the analog signal processor.

摘要： The radio receiver includes: a mixer configured to convert a received signal to an IF signal using a local oscillation signal; an IF processing section configured to limit the band of the IF signal; a detection section configured to demodulate the band-limited IF signal; a frequency control section configured to output a frequency control signal corresponding to a desired signal; and a local oscillation section configured to generate the local oscillation signal having a frequency corresponding to the desired signal according to the frequency control signal. The frequency control section outputs as the frequency control signal to change the frequency of the local oscillation signal so that the difference from the frequency corresponding to the desired signal is not more than the frequency of the IF signal, and determines one of the set values with which the corresponding image signal strength is lowest as the frequency control signal.
