1. A timing detection device, comprising:
processing circuitry configured:
to generate a main reference code consisting of the same code as a code for synchronization included in a received signal;
to generate, by using a portion of the same code as the code for synchronization, an auxiliary reference code consisting of a code configuration different from the main reference code and suppressing the generation of a main lobe during a correlation process;
to output a first correlation result by correlating the received signal with the main reference code;
to output a second correlation result by correlating the received signal with the auxiliary reference code; and
to subtract the first correlation result from the second correlation result.
