A Tutorial on SISO and MIMO Channel Capacities

چکیده
This is a tutorial article presenting comparison between single input single output and multi input multi output wireless channel. We have compared Shannon ergodic capacity of SISO link and its different realizations with MIMO wireless channel. It is shown that wireless channel capacity increases linearly with the increase of multiple antennas both at transmitter and receiver. MIMO wireless link capacities when transmitter and receiver both have perfect knowledge of channel matrix, only transmitter has the channel matrix knowledge and when only receiver has the channel knowledge are presented. MIMO channel decomposition using eigen values and singular values decomposition methods is presented. Key Words– Single Input Single Output (SISO), Multi Input Multi Output (MIMO), Signal to Noise Ratio (SNR), Shannoncapacity.

MIMO capacities for different antenna arrangements based on double directional wide-band channel measurements
The performance of future wireless communication systems can be highly increased by utilizing multiple antennas at both sides of a wireless communication link. A concept for MIMO double directional wide-band channel measurements is presented and high-resolution channel parameter estimation is applied. Furthermore, a procedure, where MIMO capacities are obtained by one single SISO channel transf...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Multiple-input multiple-output (MIMO) has been accepted as a promising technology for its potential to achieve low bit error rate (BER) by space time coding [1] or to achieve large capacity by multiplexing [2]. MIMO multiplexing has been widely adopted to realize high speed data communications. The capacity of MIMO systems in the point-to-point transmission without external interferences has be...
متن کاملLow SNR Characterization of the Channel Capacity of Generalized Fading Channels
This paper aims to characterize the low signal-to-noise ratio (SNR) capacity of generalized fading channels. The work was performed during my graduation internship at King Abdullah University and Science and Technology. The multiple-input multiple-output (MIMO) Rayleigh fading channel and the single-input single-output (SISO) Log-normal shadowing channel are successively considered. General exp...
