Correctable symbol errors
16
Storage overhead
14.3498%
Parity symbols
32
Code rate
87.451%
RS(255,223), used in CDs and QR codes, can correct up to 16 symbol errors per 255-symbol block.
Formula and working
Correctable symbols t = (n − k) ÷ 2; Overhead % = ((n − k) ÷ k) × 100
- 1
Collect the inputs
Total symbols (n) = 255; Data symbols (k) = 223
- 2
Apply the formula
Correctable symbols t = (n − k) ÷ 2; Overhead % = ((n − k) ÷ k) × 100
- 3
Result
Correctable symbol errors = 16
