Abstract
A multi-antenna apparatus of a multi-input multi-output (MIMO) communication system for compressing and decompressing a frequency domain digital signal are provided, wherein a data channel type of each frequency-domain digital sub-signal of the frequency-domain digital signal is determined by a radio frame structure map (π). The multi-antenna apparatus includes a respective compressor and a respective decompressor associated to each data channel type, and is configured, for each frequency-domain digital sub-signal of the frequency-domain digital signal, to compress, at a first module, the frequency-domain digital sub-signal using the compressor associated to the data channel type of the frequency-domain digital sub-signal, and, for each compressed frequency-domain digital sub-signal, to decompress, at a second module communicating with the first module via an FH link, the compressed frequency-domain digital sub-signal using the decompressor associated to the data channel type of compressed frequency-domain digital sub-signal.
