Upgraded Approximation of Non-Binary Alphabets for Polar Code Construction
Arash Ghayoori, T. Aaron Gulliver
An algorithm is presented for approximating a single-user channel with a prime input alphabet size. The result is an upgraded version of the channel with a reduced output alphabet…
Enumerating Some Fractional Repetition Codes
Srijan Anil, Manish K. Gupta, T. Aaron Gulliver
In a distributed storage systems (DSS), regenerating codes are used to optimize bandwidth in the repair process of a failed node. To optimize other DSS parameters such as computati…
On the Construction of Radio Environment Maps for Cognitive Radio Networks
Zhiqing Wei, Qixun Zhang, Zhiyong Feng +2
The Radio Environment Map (REM) provides an effective approach to Dynamic Spectrum Access (DSA) in Cognitive Radio Networks (CRNs). Previous results on REM construction show that t…
Constructing Polar Codes Using Iterative Bit-Channel Upgrading
Arash Ghayoori, T. Aaron Gulliver
The definition of polar codes given by Arikan is explicit, but the construction complexity is an issue. This is due to the exponential growth in the size of the output alphabet of…
