Commonality of various algorithms is analyzed based on the research of algorithms commonly used digital signal processing and a reconfigurable cell is proposed. A reconfigurable system with the cells is designed, which is widely used in a variety of digital signal processing. The principle and method of using this system are discussed with the basic algorithms of digital signal processing - multiplication...
One of the most important signal processing method in digital signal processing discipline is speaker identification method (SIM). Because of the difficult nature of speech signals and their fast variation with time, the wavelet transform is used to reduce the complexity of such signals. In this paper two identification methods are presented based on Continuous Wavelet Transform CWT. The first method...
This paper is about implementing a LINC amplifier utilizing DSP in a DAMPS wireless system. First, the theory behind LINC amplifiers is presented. Then the I-Q representation of signals is studied. Followed by a look at pi/4 QPSK schemes. Then, wepsilall show how to apply a LINC amplifier to a pi/4 QPSK modulation scheme in a digital environment, and give the equivalent RF circuit. The digital concerns...
