To write a MATLAB simulation code for a mixed THz-RF wireless communication system, you will need to:

Here is an example of a MATLAB code for a mixed THz-RF wireless communication system:

Matlab

function simulate_mixed_thz_rf_system() % Define the parameters of the system thz_carrier_frequency = 100 GHz; thz_bandwidth = 1 GHz; rf_carrier_frequency = 2.4 GHz; rf_bandwidth = 200 MHz; % Generate the transmit signals for the THz and RF links thz_transmit_signal = tone(1, thz_bandwidth); rf_transmit_signal = qpsk_modulate(rand(1, rf_bandwidth)); % Model the propagation channels for the THz and RF links thz_channel = AWGNChannel(thz_bandwidth); rf_channel = RicianChannel(rf_bandwidth, 10 dB); % Calculate the received signals at the receiver thz_received_signal = thz_channel * thz_transmit_signal; rf_received_signal = rf_channel * rf_transmit_signal; % Demodulate the received signals to recover the data thz_data = demodulate_tone(thz_received_signal); rf_data = demodulate_qpsk(rf_received_signal); end

This code defines a mixed THz-RF wireless communication system with a THz carrier frequency of 100 GHz, a THz bandwidth of 1 GHz, an RF carrier frequency of 2.4 GHz, and an RF bandwidth of 200 MHz. The transmit signals for the THz and RF links are generated using the tone and qpsk_modulate functions, respectively. The propagation channels for the THz and RF links are modeled using the AWGNChannel and RicianChannel functions, respectively. The received signals at the receiver are calculated using the convolution operation. The data is then demodulated from the received signals using the demodulate_tone and demodulate_qpsk functions.

This is just a simple example of a MATLAB code for a mixed THz-RF wireless communication system. The specific implementation of the code will vary depending on the specific parameters of the system.

Dear Sir,

Thank you so much for the response. This is a great approach and with this approach we can generate and receive the mixed THz-RF wireless system parallelly .

I want to use decode and forward scheme for two hop {Source(S)-Relay(R)-Destination(D)} mixed THz-RF wireless system with the consideration of Hop-1(S-R) operating at THz frequency range and hop-2(R-D) operating in RF frequency band.

I consider signal transmitted from source (S) is demodulated at relay(R) and retransmitted to destination (D) and finally it is demodulated at D { in particular a MPSK signal is transmitted from the source over alpha-mu fading and received at R and retransmitted from R to D over rayleigh fading and finally demodulated at D}.

I want to simulate BER and Outage probability of this scheme. Analytically I have observed that the performance of the considered system are constrained from the quality of the worst link {the link (S-R link or R-D link) having minimum Eb/N0}.
