Suppose to carry 3 bit a bit information, then the baud rate is the 1/3 of transmission rate, so how to improve the transmission rate? Can't understand the purpose of this way, please advice

CodePudding user response:

You must first understand the baud rate, data rate and the concept of channel capacity,
Secondly, according to the Nyquist baud rate is a channel of the physical properties of decision, that is to say, in your problem environment, baud rate is a constant value,
According to the formula R=B * Log2 (data rates) N (N for element types), carried by the question a bit 3 bit of information, the Log2 N=3, R=3 B, under the condition of invariable in B, data rate raised three times, namely transmission efficiency!
