DesignandDSPrealizationofan0FDMreceiver
- 设计了一个OFDM接收机，并采用1fI公司的TMS320C6416芯片进行实现。在假设理想 同步的前提下，该系统进行了FFT变化、使用了Ls(最小二乘法)进行信道估计，并且采用了 QPSK算法进行解调。最后将接收机输出数据与发端数据进行比较，在不同信噪比情况下计算其 误码率，得出了比较理想的结果。-An OFDM receiver is designed in山is paper and realized on the platform of the 1MS32OC6416 chip

16QAM_soft_demapping
- This document is about 16 QAM demapping of received data. But its a soft demapping method based Log likelihood ratio(llr). So results can be used as inputs for viterbi decoder or turbo decoder. It is very usefull to decrease BER for communication sys
program4_qpsk_baseband_without_inbuilt_function.z
- simulation of a bpsk and qpsk awgn channel. the bpsk and qpsk symbols are passed through a awgn channel and received over various snrs and ber plots
P3
- Perform base band QPSK modulation of a bit stream: (a) without using in-built function, (b) using in-built function. Pass it through an AWGN channel and plot SNR versus BER of the received signal.
P4
- Aim: To pass a (a) BPSK signal (b) QPSK signal through a flat-fading Rayleigh Channel and observe SNR versus BER plot of the equalized signal.
