摘要
介绍了一种比ＧＭＳＫ具有更优的频谱特性、频谱利用率及更强抗衰落性能的线性窄带调制解调技术（π／４ＱＰＳＫ），并给出了它的ＤＳＰ实现和相应的性能。
This paper presents a kind of linear narrowband modulation & demodulation technology,named π/4QPSK (π/4 shifted QPSK),which possesses features of better spectrum specification,spectrum utilization ratio and stronger anti fading performance over GMSK etc.DSP based implementation and performance is presented.
