A New Cooperative Spectrum Sensing Scheme for Cognitive Ad-Hoc Networksion efficiency. It is well known that the success of cognitive radio depends heavily on fast and efficient spectrum sensing that can be very difficult in practice. Toward this end, this paper introduces a new guard-resident collaborative spectrum sensing topology for a cognitive ad-hoc network. In p

Iterative DS-CDMA Anti-interference Technique Based on Interference Power Cognitionference is broadband digital modulation signal and desired signal is direct sequence spread spectrum(SS) signal. The power ratio of SS signal and interference is detected by cognitive method, and threshold value is calculated meanwhile. After that, the order of iteration is chose based on power rati

Signal Detection for Joint Distributed Space-Time Coding in Asynchronous Cooperative Cellular Systemsed for an asynchronous cooperative cellular system utilizing the efficient joint distributed space-time coding (J-DSTC). Simulation results demonstrate that the proposed scheme outperforms the conventional J-DSTC equalization scheme in suppressing the interference at the destination upon receiving

A Novel Transmission Scheme Based on Sine/Chirp Hybrid Carrierssed, sharing same frequency and time resources. The issues of interferences between users adopting different type carriers are investigated, and interference suppression approaches based on the fractional Fourier transform (FRFT) are proposed.

Study on Frequency Synchronization in 3GPP LTE System for FDD and TDD Modesx (FDD) and time division duplex (TDD) modes. The proposed method includes coarse frequency offset estimation (FOE) using primary synchronization signal (PSS) based correlation in time domain, and fine FOE using phase difference between PSS and secondary synchronization signal (SSS) in frequency dom
