Patent ID: 7457348

Claim:
A transmitting apparatus for communicating information in a multi-node communication network, comprising: a spreading code sequence generator for generating spreading code sequences from a set of spreading code sequences, said set of spreading code sequences being selected from a plurality of subsets of the set of spreading code sequences associated with the transmitting apparatus and said spreading code sequences at least partially being generated by combining contents of specified stages of a first shift register with contents of specified stages of a second shift register; and a transmitter for simultaneously transmitting first I and Q signals during a first time interval, and simultaneously transmitting second I and Q signals during a second time interval, said first I and Q signals each including an individual spreading code sequence of a first subset from said set of spreading code sequences and said second I and Q signals each including an individual spreading code sequence of a second subset from said set of spreading code sequences, wherein at least one of said first and second subsets from the set of spreading code sequences includes more than one spreading code sequence.
