1. Chung, Yi-Hsueh. Performance Comparison of Clipping and Maximum Likelihood Decoding Schemes for Linear Block Code over Impulse Noise Channels.

Degree: Master, Communications Engineering, 2014, NSYSU

The major degradation of the performance by OFDM technique in a power line communication system comes from impulse noises. In order to overcome the effect of impulse noises, a clipping method has been proposed and verified as an efficient technique. This paper, however, proposes a method by maximum likelihood decoding in the time domain instead of frequency domain in the traditional OFDM system. This paper then conducts computer simulation to compare the proposed scheme with the clipping method under the system, in which the linear block code and OFDM systems are utilized. The simulation result shows that the proposed method outperforms the clipping method proposed in the literature.

2. Xie, Sheng-You. Study of Optimization of Sensor Node Deployment to Reconstruct Random Signal Field.

Degree: Master, Communications Engineering, 2014, NSYSU

The problem of the reconstruction of a Gaussian random field using a finite number of sensor nodes has been considered in the literature. In this problem, after the sensor deployment, each deployed sensor node will report its sensor observation taken at its location to a fusion center, in which the reported measurements are used to reconstruct the whole random field, i.e., not only estimate the statuses present at the deployed sensor locations, but also estimate the statuses at the spatial points without sensor nodes. Therefore, it is possible to reconstruct the whole Gaussian random field using a finite number of sensor nodes. However, to improve the reconstruction performance, it is necessary to increase the number of sensor nodes, transmission bandwidth, and the power consumption. This thesis, however, proposes a new method of sensor deployment. Specifically, we incorporate the censoring sensors approach into the sensor deployment strategy. The results shows that the proposed scheme can achieve a lower mean square error (MSE) and reduce the power consumption by only slightly increasing the number of sensor nodes.

3. Chen, Ping-chu. A Novel Timing Estimation Method for OFDM Systems.

Degree: Master, Communications Engineering, 2007, NSYSU

In this thesis, a novel training sequence is proposed for timing offset estimation in orthogonal frequency division multiplexing (OFDM) systems. The proposed training sequence and the derived timing offset estimator are proved to outperform traditional schemes. In timing estimation of OFDM systems, the scheme proposed by Schmidl [4,5] is perhaps the most well-known one. However, Schmidlâs scheme has a plateau in timing metric, which substantially degrades system performance. In this thesis, simulation experiments are conducted to evaluate the performance of the proposed timing offset estimator and the mean square error (MSE) is adopted as the performance measure. Simulation results demonstrate that the performance of the proposed scheme not only improves Schmidlâs scheme, but also outperforms Minnâs [9] and Parkâs [10] schemes. Advisors/Committee Members: Shiann-Shiun Jeng (chair), Chih-Peng Li (committee member), Tsang-Yi Wang (chair), Yang-Fang Chen (chair).

Subjects/Keywords: Timing offset estimation
