Abstract :
In this paper a comparison of several narrowband interference (NBI) suppression methods for Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) digital wireless communication systems with Orthogonal Space-Time Block Coding (OSTBC) is done. Each of the methods is analyzed in respect of its computational complexity parameters and the performance of MIMO system. When an NBI suppression method is implemented, the trade-off between performance and computational complexity is analyzed by introducing a pricing coefficient.
