چکیده
Orthogonal Frequency Division Multiplexing (OFDM) is a multi–channel modulation technique that makes use of Frequency division multiplexing (FDM) being modulated by a low bit rate digital stream. The main reason of using OFDM is because here the symbol detection is easy and also to increase the robustness against frequency selective fading and narrow band interference. Certain parameter like CFO (carrier frequency offset),I/Q imbalance (inphase and

Compensation of IQ-Imbalance and Phase Noise in MIMO-OFDM Systems
The degrading effect of RF impairments on the performance of wireless communication systems is more pronounced in MIMO-OFDM transmission. Two of the most common impairments that significantly limit the performance of MIMO-OFDM transceivers are IQ-imbalance and phase noise. Low-complexity estimation and compensation techniques that can jointly remove the effect of these impairments are highly de...
