- Bit error probability curve for QPSK mimo 1*2, Bit error probability curve for QPSK mimo 1*4-Bit error probability curve for QPSK mimo 1*2, Bit error probability curve for QPSK mimo 1*4
C1
- This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB
QPSK
- Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
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.
