- 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
BER
- 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 th
GMSK
- 为了提高移动通信系统中数据传输的有效性能,降低GMSK调制系统的误码率. 首先对GMSK调制系统进行分析,得到不同BT值GMSK调制的移动通信系统误码率和带宽的关系.通过引入具有纠错性能的编码技术,降低信息传输的误码率,提高系统的有效性. 本文给出了引入编码技术的GMSK调制系统的仿真模型,仿真结果表明,在相同的信噪比下,系统的误码率降低了1～2dB.-This paper mainly intends to improve the performance of the communicatio
uncodedBER
- the file which is uploaded is the uncoded systtem technique which we simulated. it gives the BER vs Snr curve.The un-coded system is simulated is by using randomly generated numbers and it s passed over the AWGN channel.the output of the matlab file
BERvsSNR
- Matlab code for explain the relation between BER and SNR for different Modulation-Matlab code for explain the relation between BER and SNR for different Modulation
ASK_FSK_PSK
- this file content simple example about modulation bit stream.the type of modulation is (FSK,PSK and ask) after modulation data send and received after that show the relationship between signal to noise ratio (snr) and the bit error rate (ber).....
dgds
- This gives BER vs SNR for BPSK theoretical and Simulation
P2
- To transmit a BPSK modulated signal over an AWGN channel and observe variation of BER with SNR of the channel.
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.
