Title: RADIO SYSTEM AND DECODING DEVICE FOR DISTRIBUTED COMPRESSION
Abstract:
The disclosure relates to a radio system (710) comprising a plurality of radio units (711, 721, 731), each radio unit, comprising: a receive interface (712, 722, 732), configured to receive at least one radio signal,yk, over a multiple-input multiple-output, MIMO, radio channel; compression parameters from a decoding device (740); a compressor (717, 727, 737) configured to generate a codeword signal, λk, based on the compression parameters by encoding the at least one radio signal yk with a lattice based distributed code; and a transmit interface (715, 725, 735), configured to transmit the codeword signal λk to the decoding device (740). The disclosure further relates to a decoding device (740), comprising: a receive interface, configured to receive from a plurality of radio units (711, 721, 731) a plurality of signals, λk, over a plurality of links, each signal λk corresponding to a compressed radio signal yk, wherein the compressed radio signal yk carries a plurality of messages,ω1, from a plurality of users; a decompressor (750), configured to decompress the plurality of signals λk with a nested lattice based distributed code to provide a plurality of decompressed radio signals, ŷk a decoder (760), configured to decode the plurality of decompressed radio signals, ŷk, to recover the plurality of messages; a controller, configured to determine compression parameters based on the decoder structure and based on a correlation of the received signals; and a transmit interface configured to transmit the compression parameters to each of the plurality of radio units (711, 721, 731).
