—To approximate the exact peaks of continuous-time orthogonal frequency division multiplexing (OFDM) signals, four times oversampling is usually employed for discrete-time OFDM s...
Abstract— OFDM systems are susceptible to receiver impairments such as IQ imbalance and phase noise. These impairments can severely degrade the achievable effective signalto-nois...
Orthogonal Frequency Division Multiplexing (OFDM) has been adopted in many broadband wireless communication standards. In OFDM systems, channel estimation is a crucial module in co...
— Peak-to-Average Power Ratio (PAPR) reduction in multicarrier systems with multiple transmit and receive antennas is considered. One attractive method for reducing the PAPR is t...
— This paper proposes a new method for peak to average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems using two alternative signalling ...
