The fast growing up of modern communication also contributes great improvement of audio digital broadcasting. Digital radio Mondiale (DRM)， is a newly proposed standard for digital broadcasting in AM known as ETSI ES 201 908. Meanwhile，the effective use of radio frequency of new technology implies the urgent requirement of robustness to neighborhood interference.
Recent researches on the reduction of out-of band radiation for OFDM-based technology have becoming a interesting topics by using the auxiliary carrier to achieve compatibility to original system. Zero-forcing and Tail-tracking have been proposed to reduce out-of band interference for DRM effectively. In this thesis，we are dedicated to study the combination of both technologies with different threshold. From simulation result, we found that， the combination of both approaches can achieve great improvement on the reduction of out-of-band radiation in DRM， in comparison of original proposals.
