	Abstract:Signaling pathway analysis and interpretation of the massive gene expression data is a challenging task. Clustering technology is one of the useful and popular methods to obtain these patterns inherent in the data. In order to find the best way to establish theoretical p38 MAPK signaling pathway based on Head and neck squamous cell carcinoma expression profiles, we use and compare common hierarchical clustering algorithms, such as Pearson’s correlation, Euclidean distance, Euclidean distance harmonic, spearman rank correlation, kendall’s tau, City-block distance etc, The algorithm constructs a hierarchy from top to bottom based on a self-organizing tree. It dynamically finds the number of clusters at each level.We find that,Spearman rank correlation, kendall’s tau, City-block distance, and Euclidean Distance are all fit to the analysis of the cascade composed from a MAP3K11(MLK3), a MAP2K3(MKK3), a MAPK11(P38 MAPK/β) toMEF2A in head and neck squamous cell carcinoma expression profiles. The result is consistent with the biological experimental p38 MAPK signaling pathway.

	Abstract:Multiple-Input Multiple-Output (MIMO) architecture is one of the most promising techniques to improve the quality and capacity of future wireless communication systems. In this work, we introduced adaptive frequency fractionally-spaced equalization into MIMO system. The proposed scheme can improve the BER performance of the system by oversampling and reduce the computation complexity used for channel estimation.

	Abstract:DFT-Spread OFDM (DFT-S OFDM), known as frequency-domain generation of the single-carrier frequency division multiple access (SC-FDMA), is an uplink transmission scheme of Evolved UTRA LTE. Our research mainly discusses the channel estimation of the DFT-Spread OFDM system based on different design of pilot signals, including FDM(Frequency Division Multiplexing) and CDM(Code Division Multiplexing) pilot multiplexing. Since the FDM method has been discussed elaborately in several contributions already and fully accepted, this paper focuses on the design of pilot employing CDM and corresponding channel estimation method.

	Abstract:A new backoff algorithm is proposed to enhance the performance of the IEEE 802.11 Distributed Coordination Function (DCF) which used to employ Binary Exponential Backoff (BEB) algorithm. The drastic change of Contention Window (CW) of BEB results in poor performances of fairness and delay jitter. To solve these problems, a novel algorithm called Adaptive Increment Adaptive Decrement (AIAD) is proposed, which adjusts the CW based on historical collision number. In AIAD, the adjustment of CW can properly reflect the state of medium contention, which results in improvements of fairness and delay jitter. Another backoff algorithm called Multiple Increase Linear Decrease (MILD) is considered for performance comparison. The simulation results show that AIAD outperforms BEB and MILD in general performance.

	Abstract:Based on the principle of Trellis Code Modulation（TCM）, we suppose a new scheme and Space Time Coding technology in OFDM system. Space time block coding (STBC) is applied as and inner coding to ensure the spatial diversity and TCM as the out coding to obtain coding gain. Simulation is carried on SUI-3 channel model, the method of channel estimation is also improved as well. The results show that the bit error rate (BER) can be great reduce by this improved hybrid scheme, and greater coding gain can be obtained without increase the bandwidth.

	Abstract:The quality of service management - QoSM is an important evaluation factor for service management in NGN. To evaluate QoSM efficiently, it is necessary and elementary to define an evaluation metrics and find an evaluation method. First, the evaluation metrics for QoSM based on SLA’s service management contents is proposed. Fuzzy evaluating is a method based on fuzzy mathematics. It is suitable to evaluate an object with many factors which have different infections to the object and interactions to each other. A fuzzy evaluating method to evaluate QoSM based on above evaluation metrics is designed. At last, an example of evaluating is described to illuminate that the fuzzy evaluating method for the QoSM of NGN is useful and correct.

	Abstract:The method to apply antenna selection combined with maximal ratio combining at each transmitter and receiver to realize spatial diversity in the MIMO-OFDM system is investigated in this paper. At the transmitter, the desirable antennas are selected through a set of antennas with the channel state information (CSI). The receive signals are combined with maximal ratio combining (MRC) algorithm at receiver correspondingly. In the end, the simulation is conducted in SUI-3 channel model in order to show the effectiveness of the proposed method.

	Abstract:Light-trail is a solution to providing high resource utilization and sub-wavelength support. A light-trail is a multi-point light-path, such that multiple users can take part in communication along the trail, through time (differentiated) non-overlapping connections. This multi-point flow model leads to a new set of problems in the area of protecting and restoring light-trail based networks. Conventional link protection which just protects the existed connection in the light-trail at the time of the failure is not sufficient for light-trails because of the potential of having multiple possible source-destination pairs in the same trail over time. In this paper, a novel protection mechanism is proposed for light-trail WDM mesh network, which is Backup Light-trail Expending scheme. Subsequently the performance of this scheme is evaluated and compared to conventional Connection Dedicated Protection Scheme. Numerical results obtained by simulation indicate that, Backup Light-trail Expending Scheme has a faster restoration time and better wavelength utilization
