The real-time network has always been a hot issue in different kinds of fields. This paper introduced a late-model real-time network, Time-Triggered Ethernet(TTE) with incredible performance of determinacy and reliability. A simulation model of TTE system based on OMNet++ is presented in the paper for validation. Moreover, the paper builds a TTEthernet system based on EDA technology with simplified nodes in which the main synchronization algorithm and some other functions are realized.
The variation of packet-arrival intervals is one of the problems to be solved in realizing real-time voice communications on asynchronous networks such as the Internet. Although the variation can be absorbed by a rece...

In this paper to improve the capacity and coverage of the channel in WCDMA with OFDM, a concatenation of Wideband Code Division Multiple access (WCDMA) and Orthogonal Frequency Division Multiple Access (OFDM) is used as spreading code. synchronization error which degrades the OFDM system performance is reduced by implementing synchronization algorithm which is used to estimate the offset and by using compensation technique these offsets are reduced which improves the system performance. This concept is implemented in Multi-input Multi-output (MIMO) antenna to boost the capacity of the channel for high data rate transmission.
In this paper, we gave a brief discussion of the expanded time and frequency OFDM (ETF-OFDM) system and its traditional synchronization method (the Schmidl's method). And then we present a rapid frame and symbol s...

In this paper, we gave a brief discussion of the expanded time and frequency OFDM (ETF-OFDM) system and its traditional synchronization method (the Schmidl's method). And then we present a rapid frame and symbol synchronization algorithm in this system for just detecting one training symbol instead of two training symbols in Schmidl's method. The algorithm has low calculation complexity and outperforms conventional synchronization methods.
