non-ergadic channel
Hi,
As many people said above, ergodic channel has a long term constant bit rate. Actually, guys who know random process will say that erogodic channel has same time and ensemble average. When we say the time average and the ensemble average, we have to begin from the...
Re: Entropy Rate
Hi again.
You better refer "Elements of information theory".
In the theorem 5.4.2, the minimum expected codeword length per symbol is described. Consequently, H(s) mentioned above can be expressed in detail as like, H(S) = H(s1,s2, ... ,sn)/n. Thus I can say that it is the...
Re: Entropy Rate
Hi.
You know, entropy means an uncertainty having bits unit in random variable. Thus it depends on the distribution(probability) of random variable, not an actual value of random variable. Especially, the probability in an entropy is probability mass function, that is a...
meaning of diversity
Thanks a lot!!
I understand what you mean. However, I wanna know the exact concept of "full" diversity and "degree of freedom for diversity".
degree of freedom for diversity = full diversity?
Degree of freedom is used frequently in signal analysis. I think, for example...
diversity meaning
Hi.
Thanks for attention.
I am interested in getting "diversity gain" in wireless system. In there, I heard the received signal can be interpreted by "degree of freedom"-I guess it is the number of dimension for orthogonal set- and good system should achieve full...
meaning of diversity
Hi all,
I am sorry for my simple question. however I guess some professionals can know my asking easily.
While reading paper, I wonder that what is full diversity?
Related to that, Is it good thing that degree of freedom is large?
