Multi-Linear Encoding and Decoding in MIMO Systems

The objective of future wireless communication systems is to provide reliable and high quality of service. We propose multi-linear encoding and decoding strategies by exploiting Kronecker-structured constant modulus constellation for providing low bit error ratio (BER) in the multiple-input-multiple-output (MIMO) systems. The proposed encoding schemes are output of one-layer Khatri-Rao, two-layers Khatri-Rao or two-layers Khatri-Kronecker encoding process which is equally exploited at the receiver in the decoding process to get the process gain. The proposed schemes are compared with convolutional codes with hard and soft Viterbi decoders. We observe that the proposed method outperform the latter in terms of BER.
