The timing synchronization scheme for massive MIMO systems is proposed with CCK (Complementary Code Keying) codes in this letter. Our proposed scheme is specifically designed to generate synchronization sequence with large family size. The optimal sequences can be constructed with ZCZ or LCZ based on the number of antennas. Furthermore Monte Carlo simulation results confirmed the expected detection probability for massive MIMO systems.

In this letter, we enhance Complementary Code Keying (CCK) modulation with Pseudo-Periodic Sequence. It has been proved that the new Pseudo-Periodic CCK modulation is more efficient and robust fighting against multi-path interference. In order to support our new scheme, we design and implement the corresponding simulation. The in-depth analysis of the reason why Pseudo-Periodic Sequence can do a favor to CCK is also presented and emphasized.

This letter is concerned with a channel estimation technique with interference cancellation in a wireless personal area network (WPAN) system with complementary code keying (CCK) signaling. The performance of the coherent detector based on the proposed channel estimation scheme is compared with that of a noncoherent detector, and a significant improvement of performance is observed due to the self-interference cancellation.
