Abstract: In the method of processing signals, multi-path signals are received, channel estimates for the received multi-path signals are determined, and a combining operation is applied to the multi-path signals, the combining operation being a function of a correlation matrix of the received multi-path signals, a correlation matrix of estimates for channels of the received multi-path signals, a cross-correlation matrix of the channels and channel estimates for the received multi-path signals, and the channel estimates.

Abstract: A portable and independently adjustable height work support device that among other uses, can be used as a portable sawhorse or as an adjunct to scaffolding in home and commercial applications. This device can be made out of wood or any other suitable materials such as plastic, fiberglass or metal. Some of the unique elements are that the vertical extensions enable the sides of the working surface to be adjusted evenly or independently at an angle. The apparatus comprises a base unit and an upper unit which comprises a horizontal member pivotally attached on both ends to vertical members that can be locked into the base unit at various heights. These vertical members are attached to the lower base using pegs or their equivalent such as screws or wedges if desired. The lower base also comprises upper and lower cross members that provide stability. For added stability, the vertical members slide up and down within the top portion of the leg assembly.
