In harsh and complex electric power system environments of Smart Grid, the observed signal is always disturbed by multiple signal sources, environmental noise or sudden packet loss, generating a significant challenge for reliable remote monitoring. In this paper, we propose a new post-processing detecting scheme for wireless data transmission in the distributed monitoring system to highly tolerate...
Interference is a major limiting factor for wireless communications. When interference is independent and identically distributed (i.i.d.), its statistics is invariant with time. The conventional statistical analysis can be used to mitigate the interferences. However, when the interferences are non-i.i.d., few signal processing techniques are available for mitigating the interferences. The matched...
The current multiple accesses, such as CDMA, are designed for multi-user wireless communication systems in the licensed spectrum, where uncoordinated interferences can be kept to a minimum. On the other hand, the uncoordinated interferences do exist in the unlicensed spectrum, and they compromise the orthogonal properties and hence degrade the performance of the current multiple accesses. In this...
For direct sequence spread spectrum communication systems suffering interference, code-aided interference suppression technique outperforms all of the previous linear or nonlinear methods. In this paper, we proposed an improved code-aided technique which can further improve the system performance greatly by using the eigenvector sign spreading sequence proposed in this paper, which depends on the...
