Multi user MIMO detection utilizing averaged spatial whitening

#The increased processing power in mobile computing devices such as tablet computers and wireless phones has allowed the devices to be used to play audio, display multimedia, and act as a gaming platform for games of increasing complexity. These uses have also increased the need for increased communication bandwidth to transmit multimedia, download programs, and stream media from desired sources. However, the increased need for bandwidth comes at a time when substantial new bandwidth is not available. Moreover, the increased processing needs often reduces the power that is available for the communication of data, thereby making it important to minimize the use of power while maximizing the amount of data that can be transmitted in a set amount of bandwidth.

#Features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention; and, wherein:

#FIG. 1a illustrates a block diagram of a single-input single-output (SISO) wireless network in accordance with an example;

#FIG. 1b illustrates a block diagram of a single-input multiple-output (SIMO) wireless network in accordance with an example;

#Reference will now be made to the exemplary embodiments illustrated, and specific language will be used herein to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended.

#Before the present invention is disclosed and described, it is to be understood that this invention is not limited to the particular structures, process steps, or materials disclosed herein, but is extended to equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts. It should also be understood that terminology employed herein is used for the purpose of describing particular embodiments only and is not intended to be limiting.

#As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result.
