Precoding for a Class of Peak-Constrained Dirty Paper Channels with a Discrete State
Zhenyu Charlus Zhang, Anas Chaaban
The dirty paper channel (DPC) under a peak amplitude constraint arises in an optical wireless broadcast channel (BC), where the state at one receiver is the transmitted signal inte…
On Achievable Rates of Evenly-Spaced Discrete Uniform Distributions in the IM/DD Broadcast Channel
Zhenyu Charlus Zhang, Anas Chaaban
In optical wireless communications, a broadcast channel (BC) employing intensity modulation and direct detection (IM/DD) is often modelled as a peak-constrained BC. A closed-form e…
Capacity Bounds for the Two-User IM/DD Interference Channel
Zhenyu Zhang, Anas Chaaban
This paper studies the capacity of the two-user intensity-modulation/direct-detection (IM/DD) interference channel (IC), which is relevant in the context of multi-user optical wire…
Residual Clipping Noise in Multi-layer Optical OFDM: Modeling, Analysis, and Application
Zhenyu Zhang, Anas Chaaban, Mohamed-Slim Alouini
Optical orthogonal frequency division multiplexing (O-OFDM) schemes are variations of OFDM schemes which produce non-negative signals. Asymmetrically-clipped O-OFDM (ACO-OFDM) is a…
