O alinhamento de interferência (IA) no domínio temporal é importante no caso de comunicações veiculares com antena única. Neste artigo, IA cíclico perfeito baseado no atraso de propagação é estendido para o K×2 canais X com dois receptores e transmissores arbitrários K≥2, que atinge o ganho máximo de multiplexação obtendo o grau de liberdade teórico de 2K/(K+1). Deduzimos as condições de alinhamento e separabilidade e propomos um esquema geral que é flexível na definição do índice de intervalo de tempo para IA no lado do receptor. Além disso, a viabilidade do esquema proposto no espaço euclidiano dois/três é analisada e demonstrada.

Abstract: Interference alignment (IA) in temporal domain is important in the case of single-antenna vehicle communications. In this paper, perfect cyclic IA based on propagation delay is extended to the K×2 X channels with two receivers and arbitrary transmitters K≥2, which achieves the maximal multiplexing gain by obtaining the theoretical degree of freedom of 2K/(K+1). We deduce the alignment and separability conditions, and propose a general scheme which is flexible in setting the index of time-slot for IA at the receiver side. Furthermore, the feasibility of the proposed scheme in the two-/three- Euclidean space is analyzed and demonstrated.
