    Abstract: There is described a method of determining an MRC coefficient vector for a RAKE receiver. The method comprises (a) estimating a channel impulse response vector, (b) estimating a noise variance vector, (c) calculating a multiplication factor vector based on the estimated channel impulse response vector and the estimated noise variance vector, (d) calculating a modified channel impulse response vector by multiplying each element in the estimated channel response vector with a corresponding element in the multiplication factor vector, and (e) calculating the MRC coefficient vector as the complex conjugate of the modified channel impulse response vector. There is also described a corresponding device, an UWB receiver, a computer program and a computer program product.
