Comparison of DCO-OFDM and M-PAM for LED-Based Communication Systems
Jie Lian, Mohammad Noshad, Maite Brandt-Pearce
Light-emitting diode (LED)-based communications, such as visible light communications (VLC) and infrared (IR) communications, are candidate techniques to provide short-range and hi…
Positioning for Visible Light Communication System Exploiting Multipath Reflections
Hamid Hosseinianfar, Mohammad Noshad, Maite Brandt-Pearce
In this paper, we introduce a new uplink visible light indoor positioning system that estimates the position of the users in the network-side of a visible light communications (VLC…
On Sequential Elimination Algorithms for Best-Arm Identification in Multi-Armed Bandits
Shahin Shahrampour, Mohammad Noshad, Vahid Tarokh
We consider the best-arm identification problem in multi-armed bandits, which focuses purely on exploration. A player is given a fixed budget to explore a finite set of arms, and t…
Learning the Number of Autoregressive Mixtures in Time Series Using the Gap Statistics
Jie Ding, Mohammad Noshad, Vahid Tarokh
Using a proper model to characterize a time series is crucial in making accurate predictions. In this work we use time-varying autoregressive process (TVAR) to describe non-station…
Capacity of Hexagonal Checkerboard Codes
Zhun Deng, Jie Ding, Mohammad Noshad +1
In this paper, we propose a new method to bound the capacity of checkerboard codes on the hexagonal lattice. This produces rigorous bounds that are tighter than those commonly know…
Complementary Lattice Arrays for Coded Aperture Imaging
Jie Ding, Mohammad Noshad, Vahid Tarokh
In this work, we consider complementary lattice arrays in order to enable a broader range of designs for coded aperture imaging systems. We provide a general framework and methods…
Data-Driven Learning of the Number of States in Multi-State Autoregressive Models
Jie Ding, Mohammad Noshad, Vahid Tarokh
In this work, we consider the class of multi-state autoregressive processes that can be used to model non-stationary time-series of interest. In order to capture different autoregr…
Hadamard Coded Modulation for Visible Light Communications
Mohammad Noshad, Maite Brandt-Pearce
Visible light communication (VLC) systems using the indoor lighting system to also provide downlink communications require high average optical powers in order to satisfy the illum…
Hadamard Coded Modulation: An Alternative to OFDM for Optical Wireless Communications
Mohammad Noshad, Maite Brandt-Pearce
Orthogonal frequency division multiplexing (OFDM) is a modulation technique susceptible to source, channel and amplifier nonlinearities because of its high peak-to-average ratio (P…
Application of Expurgated PPM to Indoor Visible Light Communications - Part II: Access Networks
Mohammad Noshad, Maite Brandt-Pearce
Providing network access for multiple users in a visible light communication (VLC) system that utilizes white light emitting diodes (LED) as sources requires new networking techniq…
Application of Expurgated PPM to Indoor Visible Light Communications - Part I: Single-User Systems
Mohammad Noshad, Maite Brandt-Pearce
Visible light communications (VLC) in indoor environments suffer from the limited bandwidth of LEDs as well as from the inter-symbol interference (ISI) imposed by multipath. In thi…
