15.1 General Properties of Prime-Length Composite Codes

15.1 General Properties of Prime-Length Composite Codes. Let F be the binary field GF(2) and F n the vector space of all binary n -tuples. Let V i be an ( n i , k i ) binary linear code for i =1, 2, where n 1 and n 2 are relatively prime.

CHAPTER 2 : Linear codes

CHAPTER 2 : Linear codes. ABSTRACT Most of the important codes are special types of so-called linear codes. Linear codes are of importance because they have very concise description, very nice properties, very easy encoding and in principle quite easy decoding. IV054. IV054.
