摘要	A compression method is disclosed, which comprises receiving an OFDM data block comprising a plurality of complex valued data samples wherein each in-phase and quadrature sample value is represented by a first number of bits. The method also comprises calculating an average of absolute sample values of the OFDM data block and mapping the average absolute sample value to a standard deviation value. The method further comprises quantizing each of the sample values using quantization thresholds scaled by the standard deviation value to produce quantized in phase and quadrature sample value representations, each comprising a second number of bits, and mapping the standard deviation value and the quantized sample value representations to an OFDM transmission frame. Corresponding de-compression method, compressor, de-compressor and network node are also disclosed.
