Orthogonal frequency division multiplexing (OFDM) is considered to be one of the promising schemes for cognitive radios (CR) systems,due to its flexibility in s
A residual carrier frequency offset (CFO) estimation scheme is proposed for the uplink of orthogonal frequency division multiple access (OFDMA) systems.Multiple
Abstract:The success of ultrasonic nondestructive testing technology depends not only on the generation and measurement of the desired waveform,but also on the
Abstract:The failure behavior of diamond-coated die was investigated experimentally and analytically through finite element method (FEM) simulation in the prese
