摘要

This paper presents a novel physical layer signalling method for OFDM systems, where the signalling information is conveyed by a pair of orthogonal Walsh sequences. Compared to SI and S2 signalling in DVB-T2 standard, the signalling with the same priority is transmitted and the computational complexity is greatly reduced by the proposed scheme. Computer simulations verify that the 7-bit signalling scheme achieves the same performance as the S2 signalling. With an increase of 50% to 11-bit signalling information, the proposed scheme could still outperform the SI signalling.
