Consequences of the Memoryless Property for Random Variables

WebDefinition 7.6, defines the capacity of a DMC. The capacity of a Discrete Memoryless Channel, p(y x) is defined as C equals the maximum of the mutual information between X and Y, where X and Y are respectively the input and the output of the generic discrete channel, and maximum is taken over all inputs distributions p(x). WebIf a continuous X has the memoryless property (over the set of reals) X is necessarily an exponential. Important Points. Continuous uniform distribution = A random variable X … WebMemoryless Property This distribution has a memoryless property, which means it “forgets” what has come before it. In other words, if you continue to wait, the length of time you wait neither increases nor decreases the probability of an event happening. Any time may be marked down as time zero.
