我看不太懂題目的意思,傳送跟接受那個部份
A certain binary communication system has a bit-error
rate of 0.1 i.e, in transmitting a single bit.
the probability of receiving the bit in error is 0.1.
To transmit messages, a three-bit repetition code is used
In other words, to send the message 1, 111 is transmitted ,
and to send the messages 0, 000 is transmitted .
At the receiver, if two or more 1s are received ,
the decoder decides that messages 1 was sent; otherwise, i.e,
if two or more zeros are received, it decides that messages 0 was sent.
Assuming bit errors occur independently .
find the probability that the decoder puts out the wrong message.
