a) Take a binary sequence of any length (for ex.1000).

b) Add white Gaussian noise using randn function.

c) Receive y seq. at receiver and take binary decision ( if received noisy bit > 0 then 1, else 0).

d) Find out total error_1 between y and x.

e) find error rate = number error/total bits transmitted.

a) Take a binary sequence of any length (for ex.100).

b) Transmit every bit if 0 as “-1,-1,-1” and if 1 as “1,1,1”

c) Add white Gaussian noise using randn function to generated 3000 length sequence.

d) Receive y seq. at receiver and take binary decision from average of 3 bits at a time( if received noisy bit > 0 then 1, else 0).

e) Find out total error _2 between y and x.

f) find error rate = number error/total bits transmitted.
