PBCC method
• PBCC is one of the data encoding methods that allows you to increase the data transfer rate by compressing the code.
• The principle of operation of the convolutional coding method is as follows. During the passage of the so-called convolutional encoder, the sequence of incoming bits changes: an additional bit or bits of information are assigned to each bit of data. Due to this, the necessary redundancy of the code is obtained, which makes the data more resistant to interference and allows them to be decrypted, even if part of the message is lost.
• As for the redundancy of the code, this parameter is adjusted depending on the needs. So, if each bit of information corresponds to two bits, then the convolutional encoding rate is 1/2, if each two bits corresponds to 3 bits, then the encoding rate is 2/3, etc.
