Abstract
A timing detection device includes a main reference code generation module, an auxiliary reference code generation module, a first correlation processing module, a second correlation processing module, and a subtraction module. The main reference code generation module generates a main reference code consisting of the same code for synchronization included in a received signal. Using a portion of the same code as the code for synchronization, the auxiliary reference code generation module generates an auxiliary reference code consisting of a code configuration different from the main reference code and without generating a main lobe during correlation processing. The first correlation processing module correlates the received signal with the main reference code and outputs a first correlation result. The second correlation processing module correlates the received signal with the auxiliary reference code and outputs a second correlation result. The subtraction module subtracts the first correlation result from the second correlation result.
