Multi-path detection method for CDMA receivers

A spread spectrum receiver capable of a multi-path detection operation, comprising:

• an antenna, responsive to a radio frequency signal containing a multi-path component, for providing a radio frequency electrical signal;
• a preprocessor, responsive to the radio frequency electrical signal, for providing a digital signal;
• and
• a receiving module, for performing a pre-selected correlation analysis of said digital signal;
• and
• a receiver processing block, for detecting said multi-path component and determining whether a distortion of said radio frequency signal caused by said multi-path component meets a predetermined condition using a pre-selected correlation analysis of said digital signal.

A system capable of a multi-path selective detection operation, comprising:

• a satellite, for providing a radio frequency signal;
• a base station, for providing a further radio frequency signal used for mobile communications;
• and
• a terminal, responsive to said radio frequency signal or to said further radio frequency signal, both containing a multi-path component, wherein said terminal contains a spread spectrum receiver capable of determining whether a distortion of said radio frequency signal caused by said multi-path component meets a predetermined condition using a pre-selected correlation analysis of said digital signal, thus implementing said multi-path detection operation.
