Abstract: The present invention relates to a code multiplexing method which employs the parallel linear or nonlinear coding whose coding rate is more than one for the multiplexing transmission. When the coding rate is more than one, the parallel input bits sequence and the parallel output bits sequence have a one-to-one relationship. The aforementioned parallel coding method is beyond the finite field, and all the parallel coding polynomial set is coprime with each other. The method includes the following steps: compositing the encoding matrix B which contains K coding vectors, forming K parallel data transmission paths which correspond to the K coding vectors, processing the convolutional coding between each data path and the corresponding coding vector where the coding constraint length is L, forming the N-dimensional output vectors by summing the result of the K convolutional coding data paths, receiving the aforementioned N-dimensional coding output vectors and taking the sequence detection.

Abstract: This invention is a method about frequency multiplex. We employ numbers of sub-carriers whose frequency spectrum are overlapped each other to modulate the transmitted data sequences, and then we get the complex modulated signals. In the receiver point, we make use of one mapping between the overlapped signals' spectrum and the transmitted data sequences to detect the transmitted data sequences. By overlapping the adjacent sun-carriers, this invention can greatly increase the spectrum efficiency, and the more the multiplicity, the higher the spectrum efficiency. Furthermore, when the spectrum efficiency increases, the needed number of signal levels for this invention will not have exponential growth, just linear growth in stead, so the requirement for system linearity can be decreased greatly.
