A modulation system that can be used alone or in conjunction with current modulation techniques for data transmission in portable phones. The system consists of two orthogonal antennas of opposite polarization in which signals can be individually received and processed. A phase delay signal combination system allows combining the signals received on the two paths to allow selective reception of various polarizations. The rate of change between these two antennas will be different for each data signal, allowing a large increase in the number of users.
