The wireless channel suffers from attenuation due to destructive multipath in the propagation media. These forms of attenuation result in the inefficient and unreliable transmission of data over many radio channels. Some possible, but non-pragmatic, solutions to combat this degradation are to increase transmission power, antenna size, or antenna height. A realistic alternative to these solutions would be to transmit some less-attenuated replica of the signal to the receiver thereby increasing the probability that the receiver will receive a less corrupted signal. This scheme of transmission and reception is called diversity and it is the most important technique used to encounter the effects of fading in wireless communications.
