Abstract
For Space-based internet of things (S-IoT) application scenario, a Dynamic Maximum Iteration Number (DMI) scheduling decoder for LDPC codes is proposed. Distinct from traditional Static Maximum Iteration Number (SMI) scheduling LDPC decoder using fixed maximum iteration number, our DMI LDPC decoder has extra circuit to obtain the dynamic maximum iteration number, which could improves BER performance only at the expense of a slightly logic resources and a small ratio of memories, compared with conventional SMI scheme. Therefore, the DMI decoder is very suitable for the fluctuation of signal-to-noise ratio of S-IoT link.
