Fig 1 : Decoding procedure
Finalized decoding was done for 20 sets of data
Finalized decoding was done for 20 sets of data
Total No of patterns decoded/ transmitted at a time = 20
No of training times = 100
Total No of bits decoded/ transmitted = 20*100 = 2000
No of errors detected at 70 cm = 86
Bit error rate =86/2000*100 = 4.3 %
The used threshold value for color conversion from color to binary in Matlab was 0.6. The maximum accuracy was possible to observe when the threshold value was 0.6 for color conversion from RGB to binary in Matlab

Fig 2 : Bit Error Rate variation with the distance to the transmitter
It was observed that the bit error rate was minimum at 70 cm distance
