摘要

短程无线电系统，如蓝牙和DECT(数字增强无绳通信)使用GFSK(高斯频移键控)，这是一种源自MSK(最小移键控)的连续相位调制方案。在本通信中，作者讨论了基于广义最小二乘(GLS)的积分后滤波器的设计，该滤波器增加了数字限制-鉴别-积分器(LDI)接收机的鲁棒性。以MSK为例说明接收机的性能。

Least squares based post-integration filtering for robust digital LDI receivers

Short range radio systems such as Bluetooth and DECT (digital enhanced cordless telecommunications) use GFSK (Gaussian frequency shift keying), a continuous phase modulation scheme derived from MSK (minimum shift keying). In this communication, the authors discuss the design of a generalized least squares (GLS) based post-integration filter, which increases the robustness of digital limiter-discriminator-integrator (LDI) receivers. As an example, MSK is used to illustrate the receiver performance.
