### maximum a posteriori probability

kindly help me for Stat Question

A Binary Symmetric Channel (BSC) has binary (0 or 1) inputs and outputs. It outputs each bit correctly with probability 1 − p and incorrectly with probability p. Assume 0 and 1 are equally likely inputs. State the MAP (maximum a posteriori probability).

Cheers

Hi bilalcisco;

I only came across a BSC a few days ago when working on another problem.Why not show me what you have done and maybe both of us can go further than either of us singly?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

I am studying probability theory now and would probably use it in my research in wireless communication (802.11 MAC to be more specific). I am afraid I dont know anything about BSC. The above problem is just to practice and have some knowledge about probability. (:

Hi;

Where are you specifically stuck?

Hello Bobbym!!

I want to find MAP (Maximum a posteriori probability), of the above given problem. The problem image is exactly same to the exercise#16 on this page 'cnx DOT org SLASH content SLASH m11271 SLASH latest.  (I want to post the image, but dont know how to, anyway i gave the path where you could find the image.)

What is a MAP?
