Low density majority codes and the problem of graceful degradation
Hajir Roozbehani, Yury Polyanskiy
We study a problem of constructing codes that transform a channel with high bit error rate (BER) into one with low BER (at the expense of rate). Our focus is on obtaining codes wit…
Massive Access for Future Wireless Communication Systems
Yongpeng Wu, Xiqi Gao, Shidong Zhou +3
Multiple access technology played an important role in wireless communication in the last decades: it increases the capacity of the channel and allows different users to access the…
A Note on the Probability of Rectangles for Correlated Binary Strings
Or Ordentlich, Yury Polyanskiy, Ofer Shayevitz
Consider two sequences of independent and identically distributed fair coin tosses, and , which are -correlated for each , i.e. $…
Energy efficient coded random access for the wireless uplink
Suhas S Kowshik, Kirill Andreev, Alexey Frolov +1
We discuss the problem of designing channel access architectures for enabling fast, low-latency, grant-free and uncoordinated uplink for densely packed wireless nodes. Specifically…
On Low Density Majority Codes
Hajir Roozbehani, Yury Polyanskiy
We study a problem of constructing codes that transform a channel with high bit error rate (BER) into one with low BER (at the expense of rate). Our focus is on obtaining codes wit…
Convergence of Smoothed Empirical Measures with Applications to Entropy Estimation
Ziv Goldfeld, Kristjan Greenewald, Yury Polyanskiy +1
This paper studies convergence of empirical measures smoothed by a Gaussian kernel. Specifically, consider approximating , for $\mathcal{N}_σ\triangleq\mathcal{…
