Impact of I/Q Imbalance Due to Gain and Phase Mismatches on IRR, Image Leakage, Constellation Distortion, SNR and BER in OFDM Systems
Abstract: Due to its great spectral efficiency and resilience to multipath fading, orthogonal frequency division multiplexing, or OFDM, has become a popular modulation technique in contemporary wireless communication systems. Reliable OFDM reception depends on accurate channel estimate, and methods like Least Squares (LS) and Minimum Mean Square Error (MMSE) estimation are frequently used to make up for channel impairments. However, despite effective channel estimation, practical receiver performance can still be degraded …
