Abstract: Frequency domain compression of fronthaul interface for transporting frequency domain data over Ethernet includes applying Inverse Discrete Fourier Transform to frequency domain data contained in a frequency bandwidth to generate a time domain output signal in a time domain. The time domain output signal is compressed to generate a compressed time domain output signal. The compressed time domain output signal is transmitted over a fronthaul interface to a remote unit. The compressed time domain output signal is decompressable at the remote unit to generate a decompressed time domain output signal. Discreet Fourier Transform is applied to the decompressed time domain output signal at the remote unit to recover the frequency domain data.
