- | Lab1 involves quite a bit of work. | + | Hi Everyone! |
+ | |||
+ | I have a question about Lab 2. When it asks for the symbol error, what does it mean? I think that for 16-QAPSK, each " | ||
+ | |||
+ | But there is another way to think about it where we can consider the output | ||
+ | |||
+ | Thanks! | ||

+ | Hi Hassan, | ||
+ | |||
+ | The definition of a symbol is what you can transmit through the channel at a given instance... In both cases in our lab our Baud rate is 1 symbol/ | ||
+ | |||
+ | Example: | ||
+ | |||
+ | Source data: | ||
+ | |||
+ | 1 0 1 0 0 0 1 1 1 0 1 0 0 1 0 1 | ||
+ | |||
+ | 1 0 1 0 1 0 1 1 1 1 1 0 1 1 0 1 | ||
+ | |||
+ | Where the error rate is 3/16 errors per bit | ||
+ | |||
+ | Now in the first case each symbol is two consecutive bits: | ||
+ | |||
+ | The error rate is 3/8 errors per symbol. | ||
+ | |||
+ | Now in our second case each symbol is four consecutive bits: | ||
+ | |||
+ | The error rate is 3/4 errors per symbol. | ||
+ | |||
+ | Hope it helps, and hope someone will correct me if I am wrong :) | ||
+ | |||
+ | Regards, | ||
