Abstract
The present invention is concerned with an apparatus and a method of jumping a composite PN code from a current phase position to a desired predetermined phase position so as to enhance acquisition of a composite PN code. The apparatus includes a plurality of individual PN code generators which are connected to a code combiner to produce a composite PN code. Each of the individual PN code generators is driven by its own timing gate for supplying synchronized clock pulses to its own PN code generator. A master clock is connected to a timing gate before being connected to the individual PN code generators. An inhibit input at each of the individual timing gates is provided so that the individual PN generators may be inhibited a predetermined number of clock pulses which causes the PN code generated to be inhibited and has the effect of jumping the PN code a desired number of phase positions.
