Methods and apparatus for discovering codeword decoding order in a serial interference cancellation (SIC) receiver using reinforcement learning

An apparatus for decoding codewords in a multiple-input-multiple-output (MIMO) communication network, the apparatus comprising:

• a decoding order determination circuit that determines a decoding order to decode codewords based on a state space and a decoding policy;
• a reward determination circuit that receives decoded codewords and determines a reward based on decoding results;
• a policy update circuit that updates the decoding policy based on the decoding results and the state space;
• a state interface that updates the state space based on the decoding results;
• and
• wherein the decoding order determination circuit generates an updated decoding order based on the state space and the decoding policy.
