A Common Symbol Timing Offset Synchronization (post FFT) Method for OFDM Systemt only cause inter-symbol interference (ISI) but also introduce inter-carrier interference (ICI) duo to the loss of orthogonally among all sub-carriers. In this paper, we proposed an improved method which can not only get better estimation performance but also decrease computation complexity that ne

Statistical QoS Driven Power and Rate Allocation over Rayleigh Fading Cognitive Radio Links links. Specifically, we consider the scenario that one secondary link coexists with one primary link by sharing particular portions of the spectrum. Our proposed power and rate allocation scheme aims at maximizing the system effective capacity, which can be seen as the maximum arrival rate supporte

Analysis and Implementation of a Precise Paging Mode in Co-LAC for 2G/3G Convergence Core Networks wthe same location, too much extra network traffic is caused by paging signals and location updates within the 2G and 3G networks. In this paper, we propose a new method to reduce the traffic of both paging signal and update messages by path diversity. Theoretical analysis is shown and implementation

A Novel Image Transmission System Based on Joint Source-Channel Codingcket in a rate-distortion sense. Because of the noise in transmission channel, the channel and the channel code information had been introduced to the source image coding. The image coding is based on wavelet packet, and a bit plane coding algorithm have been used for the wavelet packet sub-band cod

A Simplified Fair Scheduling Algorithm for Multiuser MIMO Systemn and fairness is a key point. Although the PF algorithm ensures the fairness of the system, the sum-capacity is restricted. We improves the PF algorithm, and achieve a tradeoff between the multiplexing gain and fairness. The simulation results show the proposed algorithm can get the multiplexing ga
