Abstract :
In this paper we present a flexible MIMO-OFDM system concept for research purposes. Algorithms for multiplexing pilot tones into MIMO-OFDM signals are reviewed. A general formulation for using orthogonal pilot sequences that extent across multiple OFDM symbols is given. Simulations are carried out to evaluate the performance of the algorithms. Transmissions are performed on a MIMO laboratory system in an indoor LOS (line of sight) environment with various parameters to validate the useability of the proposed concept.
