Abstract
A transmitter using pseudo-orthogonal code includes a serial-to-parallel converter for converting serial transmission data into 9-bit parallel data, and a pseudo-orthogonal code memory for receiving the parallel data from the serial-to-parallel converter and outputting 16-bit pseudo-orthogonal code by using the received data as addresses. The pseudo-orthogonal code memory has the relationship of the input address and output code, as expressed in the following equation:()=0.5×((−1)(−1)(−1)(−1))where C(i) is a pseudo-orthogonal code value, i is each bit of the pseudo-orthogonal code, 0≦i≦15, and b-bare a transmission data bit stream input in the memory as addresses. Accordingly, the transmission efficiency of the transmitter/receiver using orthogonal code can be remarkably improved.
