Code for Calculating Indoor Light Intensity Distribution

This code calculates indoor light intensity distribution for visible light communication applications. It has been thoroughly tested and validated for reliability. The implementation includes ray-tracing algorithms and photometric calculations to model light propagation in indoor environments.

Construction of Girth-Twelve Column-Weight QC-LDPC Codes with Program Implementation

This program constructs quasi-cyclic low-density parity-check (QC-LDPC) codes with girth twelve and specified column weight. The code rate can be adjusted by modifying the row weight parameter (k), while the code size is controlled through the sub-matrix dimension parameter (m). The implementation involves combinatorial optimization algorithms and careful matrix construction to maintain the required girth properties.
