Error Detection & Integrity Assurance
A critical component of the demodulation process is the verification of data integrity. The USSD server employs a cyclic redundancy check (CRC) to detect any alterations or errors in the transmitted data blocks. The CRC algorithm generates a polynomial code representation of the data block, which can be expressed by the following mathematical equation:
Where
CRC(x) is the resulting CRC code.
Data(x) represents the data block expressed as a polynomial.
x(n) indicates the data is multiplied by (x) raised to the power of (n), where (n) is the degree of the generator polynomial P(x).
P(x) is the generator polynomial predefined for the particular CRC standard used.
Upon reception, the USSD server recalculates the CRC using the received data and compares it to the transmitted CRC code. If the two codes match, the data block is deemed intact. If there is a discrepancy, it indicates that the data block has been corrupted during transmission. The integrity of the entire transaction is thus ensured through this rigorous error-checking protocol, which is vital for maintaining the fidelity of blockchain communications facilitated by the SIM3 platform.
