OTFS for Automotive Radars: Waveform Optimization and Ambiguity Function Analysis

ICASSP 2025accepted

Automotive radar sensors are vital for enhancing vehicle safety and autonomy, enabling functionalities such as adaptive cruise control and collision avoidance. The performance of these radar systems is highly dependent on the selected waveform. There are several waveform options for automotive radar…

In-context Mixing (ICM): Code-mixed Prompts for Multilingual LLMs

ACL 2024long

We introduce a simple and effective prompting technique called in-context mixing (ICM) for effective in-context learning (ICL) with multilingual large language models (MLLMs). With ICM, we modify the few-shot examples within ICL prompts to be intra-sententially code-mixed by randomly swapping conten…

Range-ISL Minimization and Spectral Shaping in MIMO Radar Systems via Waveform Design

ICASSP 2023accepted

In this paper, we look at a waveform design problem for colocated Multiple-Input Multiple-Output (MIMO) radar systems. Under continuous phase constraint, we aim to minimize the range-Integrated Sidelobe Level (ISL) with a compatible spectral response. In this regard, we define the range-ISL function…

On The Asymptotic Performance of One-Bit Co-Array-Based Music

ICASSP 2021accepted

Co-array-based Direction of Arrival (DoA) estimation using Sparse Linear Arrays (SLAs) has recently gained considerable attention in array processing thanks to its capability of providing enhanced degrees of freedom for DoAs that can be resolved. Additionally, deployment of one-bit Analog-to-Digital…

One-Bit DoA Estimation via Sparse Linear Arrays

ICASSP 2020accepted

Parameter estimation from noisy and one-bit quantized data has become an important topic in signal processing, as it offers low cost and low complexity in the implementation. On the other hand, Direction-of-Arrival (DoA) estimation using Sparse Linear Arrays (SLAs) has recently gained considerable i…
