Webthe design of new schemes. For each scheme, we can compute the achievable diversity-multiplexing tradeoff curve and compare it against the optimal curve. By doing this, we can take into account both the capability of a scheme to combat against fading (through diversity gain) and its achieved spatial multiplexing gain. Therefore, the tradeoff curve The following classes of diversity schemes can be identified: Time diversity: Multiple versions of the same signal are transmitted at different time instants. Alternatively, a redundant forward error correction code is added and the message is spread in time by means of bit-interleaving before … See more In telecommunications, a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics.
