This letter presents new phase configuration schemes for systems employing reconfigurable intelligent surface (RIS)-assisted space shift keying (SSK) signaling with passive beamforming (RIS-SSK-PB).

A non-binary LDPC codes whose parity check matrix has uniform column weight 2 is constructed in this paper. The approach derives a non-binary LDPC codes from a column-weight 2 binary LDPC codes which ...
