题目:Distance distribution to received words in Reed-Solomon codes

报告人:李吉有 副教授 (上海交通大学)

 

Abstract : In this talk, we study the distance distribution problem (also known as coset weight distibution) for Reed-Solomon codes. We obtain an asymptotic formula for the number of codewords with a fixed distance to a given received word of degree $k+m$ in the standard Reed-Solomon code $[q, k, q-k+1]_q$. Previously, explicit formulas were known only for $m=0, 1, 2$.  This is a joint work with Professor Daqing Wan.
