PHY Components

Physical layer options, parameterization, and waveform generation and analysis

Communications Toolbox™ Library for the Bluetooth® Protocol functions and configuration objects model Bluetooth physical layer (PHY) processing. Use these functions to generate, analyze, and decode Bluetooth low energy (BLE) and Bluetooth basic rate/enhanced data rate (BR/EDR) waveforms that are compliant with the Bluetooth Core Specification. These features enable you to design and characterize PHY processing blocks in Bluetooth communication links. You can use this functionality as a reference in verification, performance analysis, conformance testing, and radio front-end (RF)-PHY testing. Additionally, the library includes BLE direction-finding functionality to estimate angle of arrival (AoA) and angle of departure (AoD).

End-to-End BLE PHY Simulation Using Path Loss Model, RF Impairments, and AWGN

End-to-End BLE PHY Simulation Using Path Loss Model, RF Impairments, and AWGN

Uses Communications Toolbox™ Library for the Bluetooth® Protocol to perform end-to-end Bluetooth low energy (BLE) simulation for different BLE physical layer (PHY) transmission modes in the presence of the path loss model, radio front-end (RF) impairments, and additive white Gaussian noise (AWGN). The simulation results show the estimated value of the bit error rate (BER), path loss, and distance between the transmitter and receiver.

An end-to-end simulation to measure the bit error rate (BER) and packet error rate (PER) for different Bluetooth BR/EDR physical layer (PHY) packet types by using the Communications Toolbox™ Library for the Bluetooth® Protocol. These PHY packets are distorted by adding radio front-end (RF) impairments and the additive white Gaussian noise (AWGN). The distorted Bluetooth BR/EDR waveforms are processed at the practical receiver to get the BER and PER values. The obtained simulation results show the plots of BER and PER as a function of energy-to-noise density ratio (Eb/No).
