PhDThesis

Versions 1.0 and 2.0 of this program (with all their functions) is implemented by Cristina Gómez Santamaría, Universidad Pontificia Bolivariana, Colombia. Macro and Microcell scenarios are supported, with manually configurable arbitrary array antenna configuration. For several base stations please carefully configure a cuadratic number of base stations, i.e., 4 (obtaining a 2x2 matrix), 9 (3x3 matrix), 16 (4x4 matrix)... just for easy topology configuration and generation of random scatterers. This implementation is based on the following publications:

• “A generic model for MIMO wireless propagation channels in Macro- and Microcells”, A.Molisch, IEEE Transactions on Signal Processing, Vol.52, No.1, Jan 2004.
• “The COST259 directional channel model - Part I: overview and methodology”, A.Molisch et al, IEEE Transactions on Wireless Communications, Vol.5, No.12, Dec 2006.
• “The COST259 directional channel model - Part II: Macrocells”, H.Asplund et al, IEEE Transactions on Wireless Communications, Vol.5, No.12, Dec 2006.
• “Wireless flexible personalized communications. COST259: European Co-operation in Mobile Radio Research”, L.Correia, ISBN 978-0-471-49836-0.

Two scenarios are implemented so far SemiUrban_300MHz: both NLOS and LOS single link MIMO simulations are supported. For outdoor LOS multiple link MIMO simulation is supported as well. IndoorHall_5GHz: OLOS single link MIMO simulation is supported.

The script "demo_model.m" provides an example for testing the COST 2100 model. It selects scenario, link type, and initiates the simulation. The output of demo_model.m is channel functions, with size dependent on the parameter choice and setup:

1. SISO_omni: Transfer function for SISO omni-directional antenna create_IR_omni: users have to set up the frequency separation, delta_f

2. MIMO_omni: Transfer function for MIMO omini-directional antenna create_IR_omni_MIMO: users have to set up the frequency separation, delta_f. Only 2 by 2 MIMO system is implemented.

3. MIMO_dipole: Transfer function for a theoretical antenna response for any size of lambda/2-spaced linear dipole antenna arrays. An Ntx-by-Nrx theoretical antenna array response is generated and the correponding channel transfer function is simulated.

4. MIMO_measured: Transfer function for any measured MIMO antenna response get_H: users have to provide the full antenna response at the BS and MS sides, and also the rotation of the antenna arrays. The antenna response mat file have to be the same format as 'antSample.mat' file.

The modifications are listed in document changelog.
