Abstract: By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In this class you will learn about hardware platforms that support embedded Linux, Linux kernel configuration, feature selection, installation, booting and tuning.

使用的无线通信中的天线阵列 使它成为可能估计到达 (DOAs) 的方向 撞击的波形。后者可以被利用来提高 信道估计精度或作为一项投入先进的移动 定位系统。在本文中，我们考虑的上行链路 多载波码分多址 (MC-码分多址) 网络 基站具有多个接收天线 安排在统一线性阵列中。传输发生 多径信道的目标是联合估计的 通道响应和到达角的上行信号。在这样做， 我们遵循的最大可能性 (毫升) 方法和假设， 用户传输正交训练序列，以便该任务 分离信号。这种方式，所有的未知的参数， 估计彼此独立负担得起的复杂性。 理论分析和计算机模拟，用来评估 拟议的计划和进行比较的性能 与现有的替代品。

C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.
