Patent ID: 7577190

Claim:
A method for prediction of a channel coefficient in a wireless communication device adapted to communicate over a propagation path in a mobile radio channel with multipath propagation, comprising: using a canonical random variable analysis on a signal having a known sequence to predict the channel coefficient in the wireless communication device, wherein using the canonical random variable analysis comprises: producing a past matrix P and a future matrix F from a known time series x k of estimated values of the channel coefficient, wherein x k is associated with the signal having the known sequence; solving the equation system: F=B·M+E M=A·P in order to obtain estimates Â and {circumflex over (B)}, for matrices A and B, wherein F is the future matrix, P is the past matrix, M is a memory matrix representing an intermediate set of variables and a finite number of past states of the respective channel coefficient, E is an error matrix that contains prediction error variables and represents an error in a linear prediction of the future matrix; producing a past vector p from a new time series of known estimated values of the channel coefficient; and calculating a prediction vector {circumflex over (f)} for estimated values of the channel coefficient from the equations: {circumflex over (f)}={circumflex over (B)}·m m=Â·p, wherein m is an optimum dimension portion of the memory matrix identified by ascertaining canonical correlations.
