BiD Codes: Algebraic Codes from Kernel
Anirudh Dash, K. R. Nandakishore, Lakshmi Prasad Natarajan +1
We introduce Berman-intersection-dual Berman (BiD) codes. These are abelian codes of length that can be constructed using Kronecker products of a kernel matrix.…
Subcodes of Second-Order Reed-Muller Codes via Recursive Subproducts
A P Vaideeswaran, Madireddi Sai Harish, Lakshmi Prasad Natarajan
We use a simple construction called `recursive subproducts' (that is known to yield good codes of lengths , ) to identify a family of codes sandwiched between first-…
On Locally Decodable Index Codes
Lakshmi Natarajan, Prasad Krishnan, V. Lalitha
Index coding achieves bandwidth savings by jointly encoding the messages demanded by all the clients in a broadcast channel. The encoding is performed in such a way that each clien…
Capacity of Coded Index Modulation
Lakshmi Natarajan, Yi Hong, Emanuele Viterbo
We consider the special case of index coding over the Gaussian broadcast channel where each receiver has prior knowledge of a subset of messages at the transmitter and demands all…
Low ML Decoding Complexity STBCs via Codes over GF(4)
Lakshmi Prasad Natarajan, B. Sundar Rajan
In this paper, we give a new framework for constructing low ML decoding complexity Space-Time Block Codes (STBCs) using codes over the finite field . Almost all known…
Fast-Group-Decodable STBCs via Codes over GF(4)
N. Lakshmi Prasad, B. Sundar Rajan
In this paper we construct low decoding complexity STBCs by using the Pauli matrices as linear dispersion matrices. In this case the Hurwitz-Radon orthogonality condition is shown…
