A new code design method for quasi-synchronous CDMA is proposed. The proposed scheme, based on the theory of finite projective planes, has the following advantages: orthogonality; low cross-correlation for both the quasi-synchronous mode and asynchronous mode; and low auto-correlation. Numerical autocorrelation and cross-correlation results are provided for both the proposed code design and the Walsh functions
