Abstract:
1. A transmitting apparatus for transmitting information in a multi-node communication network, comprising: an almost orthogonal code sequence generator that generates a set of almost orthogonal code sequences and generates an almost orthogonal code sequence by combining contents of specified stages of a first shift register with contents of specified stages of a second shift register, said set of almost orthogonal code sequences being selected from a plurality of subsets of a set of almost orthogonal code sequences associated with the transmitting apparatus; and a transmitter for simultaneously transmitting a first I signal and a first Q signal during a first time interval and simultaneously transmitting a second I signal and a second Q signal during a second time interval, said first I signal and said first Q signal including said almost orthogonal code sequence and a first subset of said set of almost orthogonal code sequences, and said second I signal and said second Q signal including said almost orthogonal code sequence and a second subset of said almost orthogonal code sequences not identical with said first subset, wherein at least one of said first and second subsets from the set of almost orthogonal code sequences includes more than one almost orthogonal code sequence.
