Timing mismatch in time-interleaved analog-to-digital converters (TI-ADCs) may cause a significant performance degradation in high-speed orthogonal frequency division multiplexing (OFDM) systems. To evaluate the impact of this impairment in such …
This paper presents an efficient procedure to numerically evaluate the exact bit error rate of a rectangular quadrature amplitude modulated-orthogonal frequency division multiplexing (OFDM) system that is impaired by the gain mismatch of a …
For the extremely high sampling rate and high resolution required for multi-Gigabit orthogonal frequency division multiplexing (OFDM) communication systems, time-interleaved analog-to-digital converters (ADCs) are being considered. However, in …
