Multipath channel simulation with waveform shaping, signal-to-noise ratio analysis, and power spectral density evaluation - including algorithm descriptions and MATLAB implementation approaches
This simulation processes input symbols represented as row matrices containing real or complex values with symbol rate %fs. The model incorporates Doppler shift %fd and characterizes multipath propagation using %n_delay paths with specified delay times %t_delay and power values in dB %p_delay for each path. The implementation typically involves convolution operations with channel impulse response and Doppler effect modeling.
A multipath channel simulation program with the following core components: Jakes_filter.m generates the Doppler power spectrum shape of the channel, linear_fft.m performs FFT transformation with appropriate shifting, linear_psd.m analyzes signal power spectral density, qpsk_berest.m generates QPSK signals, and random_binary produces random signal sources.
