Description: vhdl mfsk
多进制数字频率调制(MFSK)也称多元调频或多频制。MFSK系统是 2FSK(二频键控)系统的推广，该系统有 M个 不同的载波频率可供选择．每一个载波频率对应一个 M进制码 元信息，即用多个频率不同的正弦波分别代表不同的数字信号，在某一码元时间内只发送其中一个频率。-vhdl mfsk M-ary digital frequency modulation (MFSK), also known as multi-frequency or multi-frequency system. MFSK system is 2FSK (b Frequency Shift Keying) system, the promotion, the system has M different carrier frequencies to choose from. Each carrier frequency corresponds to an M-band meta-information code, which uses a number of different sine wave frequency, respectively, representing different digital signal, in a symbol time to send only one frequency.

Description: 本课程设计完成了基带线路码产生电路的设计，数字基带信号的传输是数字通信系统的重要组成部分之一。在数字通信中，有些场合可不经过载波调制和解调过程，而对基带信号进行直接传输。为使基带信号能适合在基带信道中传输，通常要经过基带信号变换，这种变换过程事实上就是编码过程。本些课题实现了这样的编码过程。-This course is designed to use VHDL hardware description language completed the base-band circuits have a code of the circuit design. Digital base-band signal transmission of digital communications systems is an important part of one.In the signal before transmission to go through the code to deal with. In digital communications, there are some occasions, not through the process of modulation and demodulation, and base-band signal for direct transmission. In order to be able to base-band signal for the base-band transmission channels, usually after a base-band signal transformation, the transformation process is in fact the process of encoding.

Description: The DVI Adaptive Differential Pulse Code Modulation (ADPCM) algorithm was first described in an IMA recommendation on audio formats and conversion practices [1]. ADPCM is a transformation that encodes 16-bit audio as 4 bits (a 4:1 compression ratio). In order to achieve this level of compression, the algorithm maintains an adaptive value predictor, which uses the distance between previous samples to store the most likely value of the next sample. The difference between samples is quantized down to a new sample using an adaptive step-size. The algorithm in [1] suggests using a table to adapt this step-size to the analyzed data. ADPCM has become widely used and adapted, and a variant of the algorithm performs voice encoding on cellular phones (allowing minimal data to be sent across the wireless network and increasing throughput).
