How to write code in MATLAB for planning wireless 5G
The process of writing code in MATLAB for planning wireless 5G is examined as both difficult and captivating. Several instructions must be adhered to while writing it. We suggest a fundamental instruction based on how to begin coding a 5G network simulation in MATLAB:
Step 1: Explain Simulation Parameters
Initially, the metrics of our 5G simulation ought to be explained in an explicit manner. It could encompass frequency band, number of antennas, bandwidth, kind of modulation, and subcarrier spacing. For instance:
simulationParams.Band = ‘n78’; % Frequency band
simulationParams.Bandwidth = 100e6; % 100 MHz
simulationParams.SubcarrierSpacing = 30; % 30 kHz
simulationParams.NumAntennas = [2 2]; % 2 Tx and 2 Rx antennas
simulationParams.ModulationType = ‘QAM16’; % 16-QAM Modulation
Step 2: Set Up the 5G NR Channel
In order to set up the 5G NR channel framework, such as MIMO arrangement, path loss systems, and delay profile like CDL or TDL, it is beneficial to employ the 5G toolbox.
nrChannel = nrTDLChannel; % Using Tapped Delay Line (TDL) model
nrChannel.DelayProfile = ‘TDL-C’; % Delay profile
nrChannel.NumTransmitAntennas = simulationParams.NumAntennas(1);
nrChannel.NumReceiveAntennas = simulationParams.NumAntennas(2);
Step 3: Create Waveform
Through the utilization of the specified metrics, we plan to produce a 5G NR waveform. The process of developing a test signal, arranging the carrier, and a kind of waveform such as TDD or FDD could be encompassed.
carrier = nrCarrierConfig(‘NSizeGrid’, 52, …
‘SubcarrierSpacing’, simulationParams.SubcarrierSpacing, …
‘NCellID’, 1);
pdsch = nrPDSCHConfig(‘Modulation’, simulationParams.ModulationType, …
‘PRBSet’, (0:51)’);
% Generate random bits for PDSCH
bits = randi([0 1], 1000, 1);
% Generate PDSCH symbols
waveform = nrWaveformGenerator(bits, carrier, pdsch);
Step 4: Simulate the Channel
As a means to simulate the impact of the wireless channel, the produced waveform ought to be travelled through the arranged 5G NR channel framework.
nrChannel.SampleRate = waveform.SampleRate;
[rxWaveform, pathGains] = nrChannel(waveform.Signal);
Step 5: Carry Out Receiver Processing
To assess the channel and balance the signal, it is significant to process the obtained waveform at the receiver. Generally, demodulation, synchronization, and channel estimation are the signal processing steps that could be included.
% Example: Channel Estimation and Equalization
[estChannelGrid, noiseEst] = nrChannelEstimate(rxWaveform, carrier, nrChannel);
eqSignal = nrEqualizeMMSE(rxWaveform, estChannelGrid, noiseEst);
Step 6: Examine the Effectiveness
As a final point, the effectiveness of our 5G simulation has to be examined. Throughput, Bit Error Rate (BER), and Signal-to-Noise Ratio (SNR), are usual parameters encompassed in this procedure.
% Example: Calculate BER
rxBits = nrPDSCHDecode(eqSignal, carrier, pdsch, estChannelGrid, noiseEst);
ber = sum(rxBits ~= bits) / length(bits);
disp([‘BER: ‘ num2str(ber)]);
