ATSC 3.0 interleavers influence in reception performance

This paper presents the performance study of the interleavers defined in the ATSC 3.0 physical layer. It must be noted that for single PLP configurations convolutional time interleaving and frequency interleaving can be used. Nevertheless, when multiple PLP configurations are used, cell interleaving, block time interleaving, frequency interleaving and subslicing can also be included. The ATSC 3.0 interleavers influence on the reception performance will be tested in stationary, pedestrian and mobile scenarios. The main objective of this paper is to measure the required signal to noise ratio (SNR) threshold for an error-free reception with and without interleavers. In addition, each interleaver's parameter configuration impact on the performance is also discussed. Consequently, each interleaver performance gain will be noted for each type of scenario. The obtained results will be useful for planning purposes.
