A Novel High rate LDPC code

Abstract

In IoT applications with remote monitoring, the data is transferred through a wireless channel. To ensure data reliability, error control coding is essential. For the high error correcting ability, the Low density parity check (LDPC) codes are used as the most popular code for error-control in many domains like telecommunication, magnetic-recording, radio application, etc. Thus the data transmitted in IoT system may be encoded by LDPC codes. This paper presents a small length LDPC code of six-by-seven. The shifted identity matrix and a lower staircase matrix are used to construct the LDPC code. These codes have very low encoding complexity. Belief-propagation is used to decode the code. In the simulation result of the code, improved performance in bit error rate is shown. The simulation result of these codes shows a good performance in the bit-error-rate.
