测试测量 基于MASON公式的多功能二阶通用滤波器设计
基于通用集成运算放大器，利用MASON公式设计了一个多功能二阶通用滤波器，能同时或分别实现低通、高通和带通滤波，也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻，所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的 ...

In this paper, we consider the problem of filtering in relational
hidden Markov models. We present a compact representation for
such models and an associated logical particle filtering algorithm. Each
particle contains a logical formula that describes a set of states. The
algorithm updates the formu ...

Computes BER v EbNo curve for convolutional encoding / soft decision
Viterbi decoding scheme assuming BPSK.
Brute force Monte Carlo approach is unsatisfactory (takes too long)
to find the BER curve.
The computation uses a quasi-analytic (QA) technique that relies on the
estimation (approximate on ...

A large body of computer-aided techniques has been developed in recent years to assist
in the process of modeling, analyzing, and designing communication systems . These
computer-aided techniques fall into two categories: formula-based approaches, where the
computer is used to evaluate complex formu ...
书籍 Stochastic Geometry and Wireless Networks Volume I
Part I provides a compact survey on classical stochastic geometry models. The basic models defined
in this part will be used and extended throughout the whole monograph, and in particular to SINR based
models. Note however that these classical stochastic models can be used in a variety of contexts w ...
