LTE Rate Matching Performance with Code Block Balancing

In this paper, we compare the performance of the LTE rate matcher for different code rates when segmentation occurs. We present that, for certain cases of segmentation where the different segments are of dissimilar size, the rate applied to each segment may be different and thus degraded overall performance may occur. We show how a simple method which balances the code rate on a per-segment basis can improve the overall block error ratio performance.
