Abstract
In a high speed, high processing gain PN spread spectrum acquisition system an analog signal comprising a high speed PN code is received and converted to a high speed digital format. A demuxer is employed to divided the high speed digital signal into lower speed multiplexed portions. The lower speed multiplexed portions of the digital signal are processed in a plurality of parallel channels which employ correlators coupled to coherent accumulators and non-coherent accumulators coupled to the output of the coherent accumulators to provide a signal having sufficient energy to permit detection of one of a plurality of partial PN replica codes as the one code which is synchronized with the received analog signal comprising a high speed PN code and to synchronize with the PN replica code generator.
