- On companding techniques for PAPR reduction in DCT SC-FDMA . . .
Simulation results, considering parameters like BER, PAPR, and power spectral density (PSD), are provided to find the best companding technique Furthermore, the results have been validated in a real-time indoor channel using a wireless open-access research platform (WARP) hardware
- Adaptive Real-Time Channel Estimation and Parameter . . .
This study addresses the challenges of real-time channel state estimation and adaptive parameter adjustment in dynamic LoRa networks, where the existing methods often fail to adapt efficiently to highly variable channel conditions
- An enhanced companding algorithm for universal filtered . . .
This enhanced scheme improves power spectral density (PSD), PAPR, and BER performance Moreover, the proposed scheme was evaluated over a multipath fading channel and was found to be more robust than other companding techniques
- Performance Analysis of Nonlinear Companding Techniques for . . .
Nonlinear companding techniques are known to be one of the effective low complexity PAPR reduction techniques for multicarrier systems In this paper, a GFDM system is evaluated using mu law companding, root companding and exponential companding techniques for efficient PAPR reduction
- Channel Estimation Techniques in Wireless Communication
The mathematical technique to characterize a wireless channel is called as Channel Estimation In this paper, we will discuss different mathematical channel models and channel estimation techniques based on Machine Learning and Deep Learning along with the necessary mathematical background
- On the selection of the best companding technique for PAPR . . .
In this paper, different PAPR reduction companding transforms are compared Results showed that companding transforms that compress large signals without affecting small signals (such as, Log companding and Tanh companding) are better than the others from a BER point of view
