Diversity processing for closed loops may include combining a plurality of received multipath signals to estimate at least one processed diversity signal based on information from at one or more common channels. MN is then deposited on a substrate, on one or more seeds or it can self nucleate on the walls of a growth chamber, to form high purity metal nitride material. The winding is composed of coils comprising wires placed between the teeth, wherein the active sides of two phase coils are shifted relatively to each other being parallel to the longitudinal axis of said inductor, and phase-wise are oppositely shifted, wherein the two phase coils are situated adjacently to a third phase coil from the opposite sides thereof.
