Abstract

A new technique for spreading code acquisition is presented. The technique utilizes a multiplicity of communication and processing techniques namely, concatenated short signature coding, Reed Solomon adaptive error/erasure decoding, and pipelining to provide the minimum possible acquisition time in severe overload CDMA and carrier offsets conditions. The overall implementation is equivalent to a very long physical matched filter but is relatively immune to the Doppler degradation. These features would be shown by analysis results. We also propose two strategies in conjunction with the new virtual matched filtering, and compare their performance to known code acquisition techniques.
