Apparatus and method for multi-path search using dual code generators

A method for a multi-path search using a dual code generator, said method detecting multiple paths occurring in a mobile communication environment and demodulating them to increase the gain of a receiver,

• wherein the dual code generator comprises first and second code generators for generating first and second search codes necessary for a multi-path search, changing a phase, and generating a search-done interrupt, the method comprising:
• (a) sending a first slewing command to the first code generator, moving as far as an amount according to the first stewing command, and standing by to receive a first interrupt for the completion of the slewing;
• (b) upon receiving the first interrupt, sending a second slewing command to the second code generator and controlling the first code generator to perform a search process according to a first search command;
• (c) upon receiving the search-done interrupt according to the first search command, sending a third slewing command to the first code generator and controlling the second code generator to perform a search process according to a second search command;
• and
• (d) reading a search result alternately using the first and second code generators and sending a new search command, said process being repeated as many times as the multi-path search is done.
