ABSTRACT:
Apparatus for generating a complex composite code for fast acquisition by multiple access users is provided which comprises a composite code generator having an in-phase channel code generator and a quadrature channel code generator for generating two linear composite codes. The quadrature channel composite code is modulated onto a carrier which is 90.degree. out of phase with the in-phase carrier. The two linear composite codes are summed together and simultaneously transmitted to the receivers. Each receiver has a plurality of components code generators which generate replica component codes for fast acquisition of the composite code. A plurality of the components codes of the in-phase composite code are derived from the like components code generators in the quadrature channel to enhance speed of acquisition without acknowledgements by the receivers that any of the components codes have been acquired.
