# Constant composition codes derived from linear codes

## TL;DR

This paper introduces a new class of linear codes with known weight distributions and constructs constant composition codes as their subcodes, some of which are nearly optimal.

## Contribution

It presents a novel method for deriving constant composition codes from linear codes, expanding the coding theory toolkit.

## Key findings

- Some codes are nearly optimal in performance.
- Explicit constructions of constant composition codes are provided.
- Weight distributions of the proposed codes are determined.

## Abstract

In this paper, we propose a class of linear codes and obtain their weight distribution. Some of these codes are almost optimal. Moreover, several classes of constant composition codes(CCCs) are constructed as subcodes of linear codes.
