Square Complex Orthogonal Designs with no Zero Entry for any Antennas
Smarajit Das, B. Sundar Rajan
Space-time block codes from square complex orthogonal designs (SCOD) have been extensively studied and most of the existing SCODs contain large number of zeros. The zeros in the de…
A Class of Maximal-Rate, Low-PAPR, Non-square Complex Orthogonal Designs
Smarajit Das, B. Sundar Rajan
Space-time block codes (STBCs) from non-square complex orthogonal designs are bandwidth efficient when compared with those from square real/complex orthogonal designs. Though there…
Low-delay, Low-PAPR, High-rate Non-square Complex Orthogonal Designs
Smarajit Das, B. Sundar Rajan
The maximal rate for non-square Complex Orthogonal Designs (CODs) with transmit antennas is if is even and if is odd, which ar…
Asymptotic Analysis of the Performance of LAS Algorithm for Large-MIMO Detection
Saif K. Mohammed, A. Chockalingam, B. Sundar Rajan
In our recent work, we reported an exhaustive study on the simulated bit error rate (BER) performance of a low-complexity likelihood ascent search (LAS) algorithm for detection in…
Large MIMO Detection: A Low-Complexity Detector at High Spectral Efficiencies
K. Vishnu Vardhan, Saif K. Mohammed, A. Chockalingam +1
We consider large MIMO systems, where by `{\em large}' we mean number of transmit and receive antennas of the order of tens to hundreds. Such large MIMO systems will be of immense…
Leveraging Coherent Distributed Space-Time Codes for Noncoherent Communication in Relay Networks via Training
G. Susinder Rajan, B. Sundar Rajan
For point to point multiple input multiple output systems, Dayal-Brehler-Varanasi have proved that training codes achieve the same diversity order as that of the underlying coheren…
