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.
