TLDR
A time asynchronous scheme for successive interference cancellation receivers that maximally suppresses the inter-user interference compared to any other time asynchronous schemes is proposed.Abstract:
Two-user non-orthogonal multiple access systems with quadrature phase-shift keying modulation are studied. A time asynchronous scheme for successive interference cancellation receivers that maximally suppresses the inter-user interference compared to any other time asynchronous schemes is proposed. Exact bit error rate (BER) solutions for the two users operating in the additive white Gaussian noise channel using the proposed scheme are derived. A simpler closed-form BER approximation for the weaker user is also presented. Compared to the symbol-synchronous scheme, numerical results show the proposed asynchronous scheme reduces the BER for the stronger signal by a factor of one-half.read more

TL;DR: In this article , an asynchronous non-orthogonal multiple access-based cyclic triangular successive interference cancellation scheme is proposed for a massive device-to-device network, which reduces the decoding complexity, energy consumption, and bit error rate of a superimposed signal received in an outband D2D network.

TL;DR: According to signal transmission characteristic, the non-orthogonal multiple access schemes are classified into four categories: scrambling based NOMA, interleaving based N OMA, spreading based NomsA and coding based NomA, where the scheme with superior performance is given.
