eleven B seven T schemes maps eleven bits binary sequence, using zero and one representing signal of one bit, with two to the power of eleven, equal to two thousands fourty eight patterns to seven trits sequence T six to zero, also known as PAM three symbols, using zero, one and two representing signal of one PAM three symbol, with three to the power of seven, equal to two thousands one hundred eighty seven patterns through the following step,
Partitioning eleven bits sequence to three grouped three B two T and leftover two bits sequence two B one T coding can achieve much higher efficiency around ninety nine dot one percent to lower bandwidth.
eleven B seven T encoding, each three B two T group do three B two T encoding. Based on bit sequence of two B one T to select either first encoding branch without the one redundant constellation point or second encoding branch with the one redundant constellation point.
eleven B seven T decoding, traverse Trits T five to T four, T three to T two, and T one to T zero field to check if any one of these fields includes the one redundant constellation point to select corresponding first or second encoding branch to decode. |
