Block transmission of multi-scale orthogonal wavelet division multiplexing (OWDM) is proposed for signaling over wideband linear time-varying channels (LTV). Such channels are bes...
— In this paper, an innovative frequency domain joint estimation algorithm of synchronization parameter and channel impulse response (CIR) in Direct Sequence Code Division Multip...
Orthogonal frequency division multiplexing (OFDM) is very sensitive to frequency offsets which result in considerable interference. Performance of the system will be exacerbated ...
— In this paper, we analyze the effects of IQ (In-phase/ Quadrature-phase) imbalances at both transmitter and receiver of OFDM (Orthogonal Frequency Division Multiplexing) system...
