Simulation codes of novel NOMA design over wireless channels
NOMA simulation is a compelling task that must be carried out by adhering to numerous guidelines. Regarding the NOMA simulation, we provide an outline, including a basic Python instance. For interpreting and simulating highly advanced NOMA models, this instance must act as a preliminary phase.
Theoretical Framework for NOMA Simulation
Across the similar frequency band, several users are functioning with various code rates and energy levels in NOMA. Using successive interference cancellation (SIC) for signal decoding and manipulating the energy field for several accesses is the major principle of NOMA. Focus on the following aspects that could be included in a simple simulation:
- User and Channel Setup: Various factors have to be specified, such as the total count of users, the overall transmit power, and their channel states.
- Power Allocation: In terms of channel states, power must be assigned to users. As an instance: for users with weaker channel states, assign increased power, especially in a simple inverse relationship.
- Signal Transmission and Reception: Across a wireless channel, the signal transmission has to be simulated. It is significant to append Gaussian noise and examine path loss.
- Decoding with SIC: The SIC procedure should be applied, in which the user decodes its signal, specifically who has the greatest channel state. From the integrated signal, the user subtracts it after decoding. Then, the subsequent user is enabled to carry out the procedure.
Basic Python Instance
Including two users and simple signal processing, a more basic NOMA setting is exhibited by this Python instance. For simulation, it offers an initial point instead of applying complete NOMA logic.
import numpy as np
# Basic parameters
total_power = 10 # Total transmit power
noise_power = 1 # Noise power
user_channel_gains = np.array([0.9, 0.2]) # Channel gains for 2 users
alpha = np.array([0.6, 0.4]) # Power allocation coefficients (must sum to 1)
# Transmit powers for each user
user_powers = total_power * alpha
# Received signal powers (assuming unit signal power)
received_powers = user_powers * user_channel_gains
# Simulating reception with additive white Gaussian noise (AWGN)
noise = np.random.normal(0, np.sqrt(noise_power), 2)
received_signals = received_powers + noise
print(“Received signal powers with noise: “, received_signals)
# Simplified decoding (without SIC for demonstration)
# Assuming binary signaling for simplicity, thresholding at 0 for bit decision
decoded_bits = np.where(received_signals > np.sqrt(noise_power), 1, 0)
print(“Decoded bits: “, decoded_bits)
Improving the Simulation
Plan to integrate the following factors to create a highly precise and advanced NOMA simulation:
- Detailed Channel Models: It is important to encompass shadowing effects, path loss, and fading (for instance: Rician, Rayleigh).
- Complex Power Allocation Schemes: For improving simulation, focus on optimization algorithms which examine various important conditions such as throughput enhancement, user objectivity, and others.
- Complete SIC Process: Consider signal decoding for users and simulate the procedural steps. For decoding faults, the capability has to be examined. On following SIC procedures, their effect has to be analyzed.
- Multiple Users and Pairing Policies: To manage enormous users, the simulation must be expanded. For NOMA, various user pairing policies have to be investigated.
Tools and Libraries
Aim to utilize particular libraries and tools, especially to carry out highly advanced simulations:
- MATLAB: For the simulations of wireless interactions, MATLAB provides a wide range of assistance. Specifically for channel modeling, enhancement, and signal processing, it encompasses built-in functions.
- NS-3 or OMNeT++: Highly intricate network contexts can be designed through these network simulators. To incorporate NOMA models using unique modules, these simulators could be expanded.
