There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Physical Layer Design and Performance Analysis for Cooperative Communication for Wireless Multi-hop Network
Committee:

Abstract:
The objective of the proposed research is primarily concerned with physical layer signal processing and performance analysis of different cooperative communication schemes in wireless multi-hop networks. A new cooperative diversity approach combining random delay and phase dithering is proposed for SC-FDE to eliminate the coordination overhead, and is proved to be very robust in different channel models; a computationally efficient equalization algorithm which can compensate large multiple carrier frequency offsets (CFOs) is developed for the OFDM distributed spatial multiplexing (DSM). For the theoretical analysis part, novel analysis and new results for point-to-point SC-FDE linear equalizer are presented; the closed form expression for the distribution of the nonzero eigenvalues of the equivalent channel matrix of multi-hop DSM are supposed to be developed.
