R(\epsilon)bits per second. If a channel of capacityCbits per second is used, then in order for any communication system to be able to achieve\epsilonmean-squared error or less with this channel it is necessary thatR(\epsilon) \leq C. This inequality can be used to determine the minimum mean-squared error obtainable for a given source-channel pair without discussing any particular communication system. As an example, the minimum mean-squared error is calculated for cases in which the analog source and additive channel noise are stationary, Gaussian processes. The performance of amplitude and angle modulation systems is compared to the theoretically ideal performance obtainable in some of these cases.">
