Transfer Function Computation for Complex Indoor Channels Using Propagation Graphs

Ramoni Adeogun, Troels Pedersen, Ayush Bharti

Abstract: This paper presents a low complexity method for computation of the transfer matrix of wireless channels in complex indoor environments using propagation graphs. Multi-room indoor environments can be represented in a vector signal flow graph with with rooms in the complex structure as nodes and propagation between rooms as branches. The transfer matrix can be computed using Masons theorem which lead to a much-reduced computational complexity.
