Phase Noise Compensation Using Limited Reference Symbols in 3GPP LTE Downlink
Kun Wang, Louay M. A. Jalloul, Ahmad Gomaa
It is known that phase noise (PN) can cause link performance to degrade severely in orthogonal frequency division multiplexing (OFDM) systems, such as IEEE 802.11, 3GPP LTE and 5G.…
Sparse Digital Cancellation of Receiver Nonlinear Distortion in Carrier Aggregation Systems
Ahmad Gomaa, Charles Chien, Ming Lei +2
In carrier-aggregation systems, digital baseband cancelation of self-interference generated by receiver nonlinearity requires the estimation of several reference signals contributi…
Multi-User MIMO Receivers With Partial State Information
Ahmad Gomaa, Louay M. A. Jalloul, Krishna S. Gomadam +2
We consider a multi-user multiple-input multiple-output (MU-MIMO) system that uses orthogonal frequency division multiplexing (OFDM). Several receivers are developed for data detec…
A Subspace Method for I/Q Imbalance Estimation in Low-IF Receivers
Ahmad Gomaa, Ayman Elezabi, Mohamed Eissa
In low-intermediate-frequency (low-IF) receivers, I/Q imbalance (IQI) causes interference on the desired signal from the blocker signal transmitted over the image frequencies. Conv…
Efficient Soft-Input Soft-Output MIMO Chase Detectors for arbitrary number of streams
Ahmad Gomaa, Louay Jalloul
We present novel soft-input soft-output (SISO) multiple-input multiple-output (MIMO) detectors based on the Chase detection principle [1] in the context of iterative and decoding (…
Efficient Soft-Input Soft-Output Detection of Dual-Layer MIMO Systems
Ahmad Gomaa, Louay M. A. Jalloul
A dual-layer multiple-input multiple-output (MIMO) system with multi-level modulation is considered. A computationally efficient soft-input soft-output receiver based on the exact…
