Probability of Error for complementary signals as function of ? sub “N”
The following worksheet specifies a 10-sample binary data signal s sub "1" in B4:B13. A random transmitted bit D sub "t" is computed in B1. The transmitted signal sT sub "i" (in C4:C13) = s sub "i" if Dt=1 and =-s sub "i" if D sub "t" =0. The Gaussian noise sequence N sub "i" SD on the first image is specified in F1. The detected signal X sub "i" is computed in E4:E13. The matched processor component s sub "i" X sub "i" is computed in F4:F13, and the matched processor output V is computed in F15. The detected bit D sub "r" is computed in D1.
The probability of error is estimated by computing the ratio of errors to transmitted data in I5 as the noise ? sub "N" varies from 0 to 14?? in steps of ?? specified in I1. The total number of data bits to be transmitted n sub "T" is specified in I2. The number of transmissions accomplished in shown in I3 and the number of errors in I4. Three VBA Macros are present:
• ResetCS resets the counts in I3 and I4.
• XmitCS increments the number of transmissions and, if an error occurs, increments the error count.
• AutoCS computes the P[error] for nT transmissions as ?N varies and displays the results in H8:I15.
