摘要： 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: c(i)=0.5×((−1)b2⊕(i1b1)⊕(i0b0) (−1)b5⊕i2⊕(i1b4)⊕(i0b3) (−1)b8⊕i3⊕(i1b7)⊕(i0b6) (−1)( b2⊕b5⊕b8)⊕i3⊕i2⊕(i1(b1⊕b4⊕b7))⊕(i0(b0⊕b3⊕b6))) where C(i) is a pseudo-orthogonal code value, i is each bit of the pseudo-orthogonal code, 0≦i≦15, and b0-b8 are 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.
