Whitepaper: Spatial Multiplexing for Outdoor MIMO-OFDM Systems With Limited Feedback Constraint

by Uppsala UniversityJan 01, 2008

Next generation mobile communication systems are expected to place stringent demands for high quality and high data rates over mobile radio channels. Recent studies on Multiple Input Multiple Output (MIMO) antenna systems with Orthogonal Frequency Division Multiplexing (OFDM) signaling have shown that spatial-frequency parallel processing at both transmitter and receiver, combined with fast adaptive transmission, is able to provide significant increases in spectral efficiency. This research paper from Uppsala University proposes a spatial multiplexing technique for the downlink of a MIMO Orthogonal-Frequency-Division-Multiplexing (OFDM) system.

Whitepaper: Entrepreneurship And Self-Finance

by Uppsala UniversityJan 01, 2008

This research paper from Uppsala University purpose is to clarify and distill some distinctive theoretical arguments for why self-finance is so important and to clarify what the barriers to self-finance look like. It contains an overview of the empirical results as well as of the more conventional theoretical views. The paper presents and clarifies the argument of the new and emerging synthesis in this area, and also discusses the barriers to self-finance and how these could be alleviated.
