Analog equalizer networks apparatus for wideband los-mimo processing

An analog equalizer network apparatus for wideband light-of-sight (LoS)-multi-input multi-output (MIMO) processing, the apparatus comprising:

• a plurality of analog equalizer networks configured to perform channel separation of input signals received through receiving antennas of N×N LOS MIMO networks, wherein
• each of the plurality of analog equalizer networks comprises:
• a power distributor configured to distribute a first input signal received through the receiving antenna of the wideband LoS-MIMO network to a first path from a first input terminal to a first output terminal, and distribute a second input signal received through the receiving antenna to a second path from a second input terminal to the first output terminal;
• a first delay line located on the first path, and configured to delay the first input signal distributed to the first path;
• a second phase shifter located on the second path and configured to shift a phase of the second input signal distributed to the second path;
• and
• a power combiner configured to combine the delayed first input signal and the phase-shifted second input signal to perform channel separation.
