SIGNAL PROCESSING APPARATUS AND SIGNAL PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18031575 titled 'SIGNAL PROCESSING APPARATUS AND SIGNAL PROCESSING METHOD
Simplified Explanation
- The present disclosure describes a signal processing apparatus and method for optimizing signal transmission in a communication system. - The apparatus includes a preprocessing unit that generates a joint matrix based on channel matrixes of subcarriers and converts parallel QAM signals into a serial QAM signal. - A judgment unit determines the constraint relationship of a constellation point in each element based on whether the constellation point needs to be extended in a constellation diagram. - A processing unit establishes a convex optimization model using the joint matrix, serial QAM signal, and determining result, and determines a joint time-domain signal of antenna channels based on the constraint relationship and convex optimization model. - A conversion unit performs a serial-to-parallel conversion on the joint time-domain signal.
Original Abstract Submitted
The present disclosure provides a signal processing apparatus and a signal processing method, the signal processing apparatus includes: a preprocessing unit configured to generate a joint matrix according to channel matrixes of subcarriers, and perform a parallel-to-serial conversion on QAM signals of the subcarriers to obtain a serial QAM signal; a judgment unit configured to determine a constraint relationship of a constellation point in each element according to a determining result obtained by determining that whether the constellation point is to be extended in a constellation diagram; a processing unit configured to establish a convex optimization model according to the joint matrix, the serial QAM signal and the determining result, and determine a joint time-domain signal of antenna channels according to the constraint relationship of the constellation point and the convex optimization model; and a conversion unit configured to perform a serial-to-parallel conversion on the joint time-domain signal.
