- W2034730257 abstract "A multiband system can flexibly create spectral holes to avoid interference between different systems. When two systems within the same frequency band coexist, the multiband system must immediately detect the signals from all users to remove unwanted interference. The complication of creating spectral holes is to obtain an occupied frequency band and an angle-of-arrival of interfering system. These parameters must be measured at the receiver of multiband system and then fed back to the transmitter. This paper presents a channel estimator with an interference detector that is developed to implement and test it's functionality in a multiband system. The proposed estimator can precisely detect the parameters before demodulation, and quickly feed back the interfering system parameters to transmitter. The effective design and the detection error rate were evaluated via verification tests in an anechoic chamber and computer simulations. The results of the proposed technique show an ability of interference detection as well as channel estimation." @default.
