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…
On some special cases of the Entropy Photon-Number Inequality
Smarajit Das, Naresh Sharma, Siddharth Muthukrishnan
We show that the Entropy Photon-Number Inequality (EPnI) holds where one of the input states is the vacuum state and for several candidates of the other input state that includes t…
Entropy power inequality for a family of discrete random variables
Naresh Sharma, Smarajit Das, Siddharth Muthukrishnan
It is known that the Entropy Power Inequality (EPI) always holds if the random variables have density. Not much work has been done to identify discrete distributions for which the…
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…
