The implementation of orthogonal frequency division multiplexing (OFDM)-based physical
layers suffers from the effect of In-phase and Quadrature-phase (IQ) imbalances in the front …

Communication receivers that utilize I/Q downconversion are troubled by amplitude and
phase mismatches between the analog I and Q branches. These mismatches are …

The implementation of OFDM-based systems suffers from impairments such as in-phase and
quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are …

Orthogonal frequency division multiplexing (OFDM) is a widely recognized modulation
scheme for high data rate communications. However, the implementation of OFDM-based …

Zero-intermediate frequency (IF)-based orthogonal frequency division multiplexing (OFDM)
transmitters and receivers are gaining a lot of interest because of their potential to enable …

There may be provided a receiver that may include a set of first filters; a first set of
downsamplers; a set of sub-band processors, the set of sub-band processors comprises a …

Orthogonal frequency-division multiplexing (OFDM) is widely adopted in narrowband
Internet of Things (NB-IoT). Nevertheless, the OFDM system is highly sensitive to the …

A direct conversion architecture reduces the cost and power consumption of a receiver.
However, a direct conversion receiver may suffer from direct current (DC) offset, frequency …

We propose a novel pilot-aided compensation scheme for carrier frequency offset (CFO) and
I/Q imbalance. The proposed scheme comprises a generalized periodic pilot and a low …
