Low-delay, High-rate Non-square Complex Orthogonal Designs
Smarajit Das, B. Sundar Rajan
The maximal rate of a non-square complex orthogonal design for transmit antennas is if is even and if is odd and the codes have be…
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…
Low-Complexity Detection/Equalization in Large-Dimension MIMO-ISI Channels Using Graphical Models
Pritam Som, Tanumay Datta, N. Srinidhi +2
In this paper, we deal with low-complexity near-optimal detection/equalization in large-dimension multiple-input multiple-output inter-symbol interference (MIMO-ISI) channels using…
A Low ML-decoding Complexity, Full-diversity, Full-rate MIMO Precoder
K. Pavan Srinath, B. Sundar Rajan
Precoding for multiple-input, multiple-output (MIMO) antenna systems is considered with perfect channel knowledge available at both the transmitter and the receiver. For 2 transmit…
Maximum Rate of Unitary-Weight, Single-Symbol Decodable STBCs
Sanjay Karmakar, K. Pavan Srinath, B. Sundar Rajan
It is well known that the Space-time Block Codes (STBCs) from Complex orthogonal designs (CODs) are single-symbol decodable/symbol-by-symbol decodable (SSD). The weight matrices of…
Generalized Silver Codes
K. Pavan Srinath, B. Sundar Rajan
For an transmit, receive antenna system ( system), a {\it{full-rate}} space time block code (STBC) transmits complex symbols pe…
