Title
Channel Capacity Analysis of the Multiple Orthogonal Sequence Spread Spectrum Watermarking in Audio Signals
Abstract
Spread spectrum techniques have recently been widely used in digital audio watermarking. In this paper, the multiple orthogonal sequence spread spectrum watermarking scheme for audio signals is presented, where multiple orthogonal sequences are used to embed parallel watermarks to improve the channel capacity. The channel capacity for the proposed scheme is derived, and the optimum number of the sequence for the maximal channel capacity is obtained. The analysis shows that the channel capacity of the proposed scheme is larger than that of the existing improved spread-spectrum (ISS) scheme.
