A novel adaptive stereo sound system is proposed. The proposed scheme consists of two parts: listener position tracking using self-generating sound signals, and space skew/crosstalk cancelation. To verify the effectiveness of the proposed system, a positioning accuracy test and a subjective listener's test were carried out. It was shown that the probability of a mean squared positioning error of less...
Due to its anti-jamming capability, chirp spread spectrum (CSS) technique has attracted much attention in the area of wireless communications. However, there has been little rigorous analysis for the performance of the CSS communication system in the presence of jamming signals. In this paper, we present analytic results on the performance of a CSS system: symbol error rate (SER) expressions are derived...
Overlap is one of the techniques for increasing bit rate in chirp spread spectrum (CSS). Although more overlaps can offer higher data throughput, more intersymbol interference (ISI) occurs, resulting in serious bit error rate (BER) performance degradation. In this paper, we analyze the influence of the overlap on CSS systems and express the maximum number of overlapped symbols that does not incur...
The maximum likelihood (ML) and suboptimum ML (S-ML) detectors are derived in the first order moving average model. The ML and S-ML detectors are employed in the antipodal signaling system, and compared in terms of the bit-error-rate in impulsive environment. Numerical results show that the S-ML detector, despite reduced complexity and simpler structure, exhibits practically the same performance as...
