uncorrelated Rayleigh fading channels [1]‚ [2]. Of course‚ real channels do not satisfy these ideal assumptions‚ thus recent work has focused on measuring and characterizing real MIMO propagation channels [3]. In parallel‚ work is continuing on efficient spacetime coding strategies that achieve the benefits of MIMO communication [4]‚ [5]. However‚ thus far there has been little work on one of the most important aspects of MIMO communication systems – the antennas that are used at both the transmitter and receiver

the environmental factors that affect MIMO capacity. These factors include channel complexity‚ external interference‚ and channel estimation error. We discuss examples of space-time codes‚ including space-time low-density parity-check codes and spacetime turbo codes‚ and we investigate receiver approaches‚ including multichannel multiuser detection (MCMUD). The ‘multichannel’ term indicates that the receiver incorporates multiple antennas by using space-time-frequency adaptive processing. The article

Mass Mass refers to the quantity of matter in an object. The SI unit of mass is the kilogram (kg). The mass of an object is a fundamental property of the object; a numerical measure of its inertia; a fundamental measure of the amount of matter in the object. Definitions of mass often seem circular because it is such a fundamental quantity that it is hard to define in terms of something else. All mechanical quantities can be defined in terms of mass‚ length‚ and time. The usual symbol for mass

It is still unknown whether the Universe created black holes with the first generation of stars or whether these exotic objects were created by the first generation of stars. Because black holes represent the most extreme physical conditions of spacetime and generate some of the most energetic phenomena following the Big Bang‚ they are the ultimate physical laboratories for testing theories of the Universe. We now know that our Universe has a "foamy" structure. The galaxies and clusters of galaxies
