Part I

Regular Concatenated Codes and Their Design

List of Symbols in Part I

General notation

  • The superscript * is used to indicate complex conjugation. Therefore, a* represents the complex conjugate of the variable a.
  • The superscript T is used to denote the matrix transpose operation. Therefore, aT represents the transpose of the matrix a.
  • The superscript H is used to indicate the complex conjugate transpose operation. Therefore, aH represents the complex conjugate transpose of the matrix a.
  • The notation e-sixcirc represents the estimate of x.
