More Information
Summary:An electronic circuit includes a baseband (BB) integrated circuit (IC) semiconductor device connected to a radiofrequency (RF) IC semiconductor device through a digital interface. The BB IC semiconductor device is configured to generate time domain uplink data including symbols. The RF IC semiconductor device has a fast Fourier transfer (FFT) module configured to convert time domain downlink data to frequency domain downlink data and an inverse fast Fourier transfer (IFFT) module configured to convert frequency domain uplink data to time domain uplink data. The digital interface is configured to transfer the frequency domain uplink data and the frequency domain downlink data between the BB module and the RF module.
