Orthogonal Pulse Design Based on Sinusoidal and Cosinusoidal Functions

In order to improve the bandwidth efficiency for the communication system effectively, a designing method for orthogonal pulse based sinusoidal and cosinusoidal functions is put forward. The orthogonal pulse is designed by parameter setting, sub-band division, parameter solution and pulse solution from the point signal character. The orthogonal pulse’s spectrum is mixed or overlapped in frequency domain. It can not only be formed little relative bandwidth signal, but also large relative bandwidth signal. The system bandwidth efficiency can reach 2Baud/Hz when the orthogonal pulse is used in information transmission.
