Narrowband Interference Cancellation Based on Priori Aided Compressive Sensing for DTMB Systems
In this paper, a novel narrowband interference (NBI) cancellation scheme based on priori aided compressive sensing (CS) for digital terrestrial multimedia broadcasting (DTMB) systems is proposed.The repeated training sequences in the transmitted symbols are exploited by differential measuring to acquire the CS measuring vector of the NBI, and for joint acquisition of the NBI support priori.Using the proposed priori aided sparsity adaptive matching pursuit (PA-SAMP) algorithm, the sparse high-dimensional NBI can be accurately reconstructed from the measuring vector of much smaller size obtained through the proposed CS-based differential measuring (CSDM) method.It is verified by theoretical analysis and simulations that the proposed method outperforms conventional anti-NBI methods under multi-path broadcasting channels.
