This letter investigates a symbol error rate (SER) performance of the downlink non-orthogonal multiple access (NOMA) scheme with symbol-level successive interfe ...

Matrix [Q] is composed by m orthogonal vectors that generate a reduction subspace into which the dynamics will be projected. Projecting the dynamics on the subspace generated by the new basis: which ...

The derivation is based on a matrix nearness problem of finding the nearest orthogonal (or unitary) matrix to the encoding matrix using singular value decomposition (SVD). The resulting transmit ...
