Abstract:
1. A channel estimator, comprising: a first stage configurable to generate a first observation scalar for a first communication path of a communication channel; a second stage configurable to generate channel estimation coefficients in response to the first observation scalar; a first Kalman filter configurable to generate in response to the first observation scalar first intermediate coefficients; a third stage configurable to generate first path estimation coefficients in response to the first intermediate coefficients; a fourth stage configurable to generate a second observation scalar for a second communication path of the communication channel; a second Kalman filter configurable to generate in response to the second observation scalar second intermediate coefficients; a fifth stage configurable to generate second path estimation coefficients in response to the second intermediate coefficients; and wherein the second stage is configurable to generate the channel estimation coefficients in response to the first and second path estimation coefficients.
