CIRCUIT AND METHOD FOR DETECTING SPACE DIVISION MULTIPLE SIGNAL

摘要

PROBLEM TO BE SOLVED: To reduce the circuit scale and achieve an excellent error rate characteristic even when the modulation multivalued number is increased in the case of receiving and detecting the space division multiple signals. SOLUTION: When the detection circuit carries out an inter-signal point distance arithmetic operation on the basis of each replica signal, real number multiplier circuits or real number circuit adder circuits in an arithmetic means for generating the replica signals are shared to reduce the circuit scale equivalent to the real number multipliers or the real number adders in an inter-signal point distance respectively section.
