Zak-OTFS Based Coded Random Access for Uplink mMTC
Alessandro Mirri, Venkatesh Khammammetti, Beyza Dabak +3
This paper proposes a grant-free coded random access (CRA) scheme for uplink massive machine-type communications (mMTC), based on Zak-orthogonal time frequency space (Zak-OTFS) mod…
Low-Complexity Detection of Multiple Preambles in the Presence of Mobility and Delay Spread
Sandesh Rao Mattu, Beyza Dabak, Venkatesh Khammammetti +1
Current wireless infrastructure is optimized to support downlink applications. This paper anticipates the emergence of applications where engineering focus shifts from downlink to…
Delay-Doppler Signal Processing with Zadoff-Chu Sequences
Sandesh Rao Mattu, Imran Ali Khan, Venkatesh Khammammetti +4
Much of the engineering behind current wireless systems has focused on designing an efficient and high-throughput downlink to support human-centric communication such as video stre…
Low-Energy Line Codes for On-Chip Networks
Beyza Dabak, Major Glenn, Jingyang Liu +5
Energy is a primary constraint in processor design, and much of that energy is consumed in on-chip communication. Communication can be intra-core (e.g., from a register file to an…
Zak-OTFS and LDPC Codes
Beyza Dabak, Venkatesh Khammammetti, Saif Khan Mohammed +1
Orthogonal Time Frequency Space (OTFS) is a framework for communications and active sensing that processes signals in the delay-Doppler (DD) domain. It is informed by 6G propagatio…
LDPC Decoders Prefer More Reliable Parity Bits: Unequal Data Protection Over BSC
Beyza Dabak, Ece Tiryaki, Robert Calderbank +1
Low-density parity-check (LDPC) codes are specified by graphs, and are the error correction technique of choice in many communications and data storage contexts. Message passing de…
Unequal Error Protection Achieves Threshold Gains on BEC and BSC via Higher Fidelity Messages
Beyza Dabak, Ahmed Hareedy, Alexei Ashikhmin +1
Because of their capacity-approaching performance, graph-based codes have a wide range of applications, including communications and storage. In these codes, unequal error protecti…
The Secret Arithmetic of Patterns: A General Method for Designing Constrained Codes Based on Lexicographic Indexing
Ahmed Hareedy, Beyza Dabak, Robert Calderbank
Constrained codes are used to prevent errors from occurring in various data storage and data transmission systems. They can help in increasing the storage density of magnetic stora…
Non-Binary Constrained Codes for Two-Dimensional Magnetic Recording
Beyza Dabak, Ahmed Hareedy, Robert Calderbank
The two-dimensional magnetic recording (TDMR) technology promises storage densities of terabits per square inch. However, when tracks are squeezed together, a bit stored in th…
Managing Device Lifecycle: Reconfigurable Constrained Codes for M/T/Q/P-LC Flash Memories
Ahmed Hareedy, Beyza Dabak, Robert Calderbank
Flash memory devices are winning the competition for storage density against magnetic recording devices. This outcome results from advances in physics that allow storage of more th…
