Exact Error Probabilities Analysis of Arbitrary 2-D Modulation-OFDM Systems with I/Q Imbalances in Frequency-Flat Rayleigh Fading Channel

چکیده
In OFDM systems, in-phase and quadrature (I/Q) imbalances generated in the analog front-end introduce interchannel interference and, consequently, error performance degradation. This paper provides an exact expression involving the twodimensional (2-D) Gaussian Q-function for the error probability of an arbitrary 2-D modulated OFDM signal with I/Q imbalances in frequency-flat Rayleigh fading channel.

The Doppler spread - gaining diversity for future mobile radio systems
In this paper the trade-off between time diversity and the inter-carrier interference (ICI) in an OFDM based MC-CDMA system is discussed. Our approach is to partially shift each spectrum of an OFDM symbol at the transmitter by using different phase shifts in the time domain at different antennas after the OFDM modulation. The summary signal at the receiver has a wider Doppler spectrum as the re...

Multiple-input multiple-output (MIMO)-orthogonal frequency-division multiplexing (OFDM) scheme has been considered as the most promising physical-layer architecture for the future wireless systems to provide high-speed communications. However, the performance of the MIMO-OFDM system may be degraded by in-phase/quadrature-phase (I/Q) imbalances caused by component imperfections in the analog fro...

In this paper we present an analytical approach to evaluate the M-QAM symbol error rate (SER) of Alamouti space time coded OFDM direct conversion receivers subject to carrier frequency offset (CFO), channel estimation errors, outdated channel state information, limited ADC resolution and flat receiver I/Q imbalance in Rayleigh time and frequency selective fading channels. The SER is numerically...
