Interference suppression in GPS receiver using space-time subspace projection techniques
A new approach was proposed for interference suppression in GPS receiver.It combines subspace projection with space-time processing based on the characters of GPS signal,noise and jammers.Space-time interference subspace is constructed using the multistage decomposition structure of the MWF based on...

| description | A new approach was proposed for interference suppression in GPS receiver.It combines subspace projection with space-time processing based on the characters of GPS signal,noise and jammers.Space-time interference subspace is constructed using the multistage decomposition structure of the MWF based on the correlation subtractive architecture.Then the optimal filter is educed.Comparing with conventional eigenvalue decomposition technique,the method proposed avoids the estimation of receive data covariance matrix and its eigenvalue decomposition,reduces the computation while the anti-jammer performance is not affected.The performance in numerical simulation demonstrates that it is effective and efficient to both narrowband and wideband interference. |
