#### **Course overview**
- communication systems
- consist of Tx, Rx and channel, the info transmitted by Tx, go through a channel than received by Rx (simple model)
- info source → source coding → channel coding → digital modulation → physical channel → digital demodulation → channel decoding → source decoding → output translation → output (more sophisticated model)
- how do we model the randomness through time?
- random variable h(t)
- random process s(t)
- what is a modulation process?
- sequences → symbols
- what we expected when we get a Rx signal?
- disturbance like channel / noise / Interference
- how we solve this problem at the Rx side?
- detector design
- what is the most critical point?
- complexity, cause we cannot expect how good the Rx side would be
- how we analysis the system at a more abstract, at a higher level?
- information theory
- but how? how can we think or perceive things in a abstract level
- what are the reasons why we need to communicate?
- at the Rx side, we lack some info from the Tx, the Tx has the uncertainty, we want to guess what the Tx wanna say
- how we measure info?
- through some correlation, if the Tx and Rx are independent of each other, than there's no information
- how we build a mathematical framework for all these communication models, long before we make any practical design?
