Através da amostragem fracionada, é possível separar componentes multipercursos e obter ganho de diversidade. No entanto, o consumo de energia aumenta à medida que a taxa de amostragem aumenta. Este artigo propõe um novo esquema para sistemas OFDM que seleciona a taxa de amostragem de acordo com a resposta em frequência do canal. Resultados numéricos por meio de simulação computacional mostram que o esquema de seleção da taxa de amostragem proposto reduz o consumo de energia ao reduzir a taxa de sobreamostragem quando a propagação do atraso é pequena.

Abstract: Through fractional sampling, it is possible to separate multipath components and achieve diversity gain. However, power consumption grows as the sampling rate increases. This paper proposes a novel scheme for OFDM systems that selects the sampling rate according to the channel's frequency response. Numerical results through computer simulation show that the proposed sampling rate selection scheme reduces power consumption by reducing oversampling ratio when delay spread is small.
