IPC: H04B7/04
Filed: 2005-01-11
Abstract: <P>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.  <P>SOLUTION: This circuit is characterized in that the circuit generates a replica signal corresponding to each transmission signal (an M-value signal corresponding to each transmission sequence) and thereafter stores each replica signal to a replica signal storage means, and produces a summated replica signal by reading the replica signals while taking into account the combination of the replica signals. Thus, while the required number of complex multipliers in a replica signal generating means is considerably reduced, the excellent error rate characteristic can be achieved.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
