The invention discloses a scrambling code number detection method, OFDM subcarriers of an OFDM symbol of the current slot received by the obtained, were scrambling descrambling, and from the OFDM sub carrier after descrambling, were extracted from the continuous subcarriers or discrete pilot subcarriers corresponding to each scrambling guide; then by the scrambling code corresponding to the power of continuous pilot subcarriers or discrete pilot subcarriers, determine the scrambling code number of the current slot, complete testing, scrambling. The invention also discloses a scramble signal detection device, the invention can effectively solve the receiver to quickly and effectively get the current time slot scrambling number problem, so as to ensure the signal between the receiver and the transmitter synchronous transmission smoothly.
