Abstract:
1. A method for receiving a radio frequency signal, said method comprising: receiving a first received signal component of the radio frequency signal using a first antenna having first properties, and receiving a second received signal component of the radio frequency signal using a second antenna having second properties, which are different from the first properties, processing the first received signal component to produce a first sampled signal component having an In-phase and a Quadrature-phase component, and processing the second received signal component to produce a second sampled signal component having an In-phase and a Quadrature phase component, producing at least one combined signal that is a linear combination of at least the first sampled signal components and the second sampled signal component, and selecting at least one set of complex values for coefficients of the linear combination so that a quality of the combined signal corresponding to each set of coefficient values is at a certain time at least equal to a quality of the one of the first sampled signal components and the second sampled signal component having the best quality.
