摘要： A radio frequency integrated circuit includes a transmitter section, and a receiver section. The receiver section includes a low noise amplifier, down conversion module, an orthogonal-normalizing module, and a baseband processor. The low noise amplifier is operably coupled to amplify the inbound RF signals to produce amplified inbound signals. The down conversion module is operably coupled to convert the amplified inbound RF signals into baseband in-phase components and baseband quadrature components. The orthogonal normalizing module is operably coupled to obtain a 1st and 2nd coefficients that are based on at least one of power of the baseband in-phase components, power of the baseband quadrature components, and/or cross-correlation between the baseband in-phase component and baseband quadrature components. The orthogonal normalizing module then normalizes an orthogonal relationship between the in-phase components and quadrature components based on the 1st and 2nd coefficients to produce normalized in-phase components and normalized quadrature components.

摘要： A radio frequency transmitter includes a digital baseband and coding module, an inverse fast Fourier transform (IFFT) module, a complex digital filter, a complex digital-to-analog converter and a radio frequency modulation module. The digital baseband and coding module is operably coupled to convert outbound data into outbound symbols in accordance with a baseband encoding protocol. The IFFT module is operably coupled to convert the outbound symbols into a complex time domain sample sequence. The complex digital filter is operably coupled to filter the complex time domain sequence such that signal strength of outbound RF signals in an exclusion RF band is at or below a specified signal strength with negligible attenuation on in-band signal strength.

摘要： A method for accurate signal detection begins by receiving a radio frequency signal, which is then converted into baseband signals. The processing then continues by performing a normalized auto correlation on the down-converted baseband signal to produce a normalized auto correlation signal. The process continues by performing a periodic pattern detection on the down-converted baseband signal to produce a normalized detected periodic signal. The process then continues by comparing the normalized auto correlation value with an auto correlation threshold and by comparing the normalized detected periodic signal with a set of thresholds. When the normalized auto correlation value compares favorably with the auto correlation threshold and when the normalized detected periodic signal compares favorably with the set of thresholds, the down-converted baseband signal is indicated to be a valid signal.
