Capacity of a MIMO system over Fading Channels

As reiterated in the previous posts, a MIMO system is used to increase the capacity dramatically and also to improve the quality of a communication link. Increased capacity is obtained by spatial multiplexing and increased quality is obtained by diversity techniques (Space time coding). Capacity equations of a MIMO...

Ergodic Capacity of a SISO system over a Rayleigh Fading channel – Simulation in Matlab

In the previous post, derivation of SISO fading channel capacity was discussed. For a flat fading channel (model shown below), with the perfect knowledge of the channel at the receiver, the capacity of a SISO link was derived as $$C = log_2 (1 + \gamma)=log_2 \left ( 1 +...

Channel Capacity & Shannon’s theorem – demystified

A chapter dedicated to Shannon’s Theorem in the ebook, focuses on the concept of  Channel capacity. The concept of Channel capacity is discussed first followed by an in-depth treatment of Shannon’s capacity for various channels Shannon’s Theorem How much data will a channel/medium carry in one second or what...
