2 Capacity of Multi-Antenna Gaussian Channels - TeletarCapacity of Multi-antenna Gaussian Channels_. Emre Telatar IAbstractWe investigate the use of multiple transmitting and or receiving antennas for single user communications over the additive Gaussian channel with and without fading. We derive formulas for the capacities and error exponents of such channels, and describe computational procedures to evaluate such formulas. We show that the potential gains of such multi-antenna systems over single-antenna systems is rather large under independence assumptions for the fades and noises at di erent receiving antennas.1 IntroductionWe will consider a single user Gaussian channel with multiple transmitting and or receiving antennas. We will denote the number of transmitting antennas by t and the number of receiving antennas by r. We will ex……
