Popis: | This paper presents an interference mitigation algorithm for coexistence of Multiple-Input Multiple-Output (MIMO) Multiband OFDM ultra wideband (MB UWB) Cognitive Radio systems with other wireless communication systems. While other interference cancellation algorithms are applied for SISO system, an improved Active Interference Cancelation algorithm for MIMO MB-UWB systems is proposed with aims to generate sufficiently deep spectral notch and minify excess transmit power of AIC tones. The efficiency of the algorithm in terms of several parameters, such as interference bandwidth, notch depth and optimization parameters is evaluated. The simulation results show that a spectral notch depth of - 70 dB and a power peak of 1 dB are achievable. |
