Generalized Distributive Law for ML Decoding of Space-Time Block Codes
Lakshmi Prasad Natarajan, B. Sundar Rajan
The problem of designing good Space-Time Block Codes (STBCs) with low maximum-likelihood (ML) decoding complexity has gathered much attention in the literature. All the known low M…

On the Sphere Decoding Complexity of STBCs for Asymmetric MIMO Systems
Lakshmi Prasad Natarajan, K. Pavan Srinath, B. Sundar Rajan
In the landmark paper by Hassibi and Hochwald, it is claimed without proof that the upper triangular matrix R encountered during the sphere decoding of any linear dispersion code i…
