Orthogonal frequency division multiplexing (OFDM) is a widely recognized modulation scheme for high data rate communications. However, the implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end anal ...
Recently, there has been considerable discussion about new wireless technologies and standards able to achieve high data rates. Due to the recent advances of digital signal processing and Very Large Scale Integration (VLSI) technologies, the initial obstac ...
Implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. The resulting distortion due to IQ imbalances can limit the achievable operating SNR at the receiver, especially when space- ...
This paper presents a robust receiver for uplink direct sequence code-division multiple access (DS-CDMA) systems. The receiver uses low order auto-regressive models to approximate the multi-path fading channel taps, and a post correlation-based uncertain m ...
Orthogonal frequency division multiplexing (OFDM) is a promising technique for multi-antenna broadband systems, since it significantly reduces receiver complexity by providing orthogonal subchannels. A drawback of OFDM systems is the performance/rate reduc ...
Phase noise causes significant degradation in the performance of Orthogonal Frequency Division Multiplexing (OFDM) based wireless communication systems. In the proposed compensation scheme, the communication between the transmitter and receiver blocks cons ...
