Analysis of GFDM as a robust 5G communication technique in noisy environment [PDF]
, 2020 One of the challenges of modulation techniques used in Fifth-Generation (5G) is their robustness in noisy environment. Conventional Orthogonal Frequency Division Multiplexing (OFDM) cannot be considered as a 5G waveform in its original form because of ...

Image matching using peak signal-to-noise ratio-based occlusion detection
IET Image Processing, 2012 A new identification mechanism is introduced for the purpose of locating objects partially occluded under low peak signal-to-noise ratio (PSNR) environment in two-dimensional grey scale image.The proposed occlusion detection is based on the utilisation of the fact that the higher the PSNR, the less the impairment of the image.

Image Compression using Orthogonal Wavelets Viewed from Peak Signal to Noise Ratio and Computation Time [PDF]
International Journal of Computer Applications, 2012 Uncompressed image data requires considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds, and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies.

Frequency-Selective PAPR Reduction for OFDM [PDF]
, 2019 We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...

Laser Diode based THz-TDS System with 133 dB peak Signal-to-Noise Ratio
, 2023 Abstract Terahertz time-domain spectroscopy (THz-TDS) has emerged as a powerful and versatile tool in various scientific fields. These include – among others – imaging, material characterization, and layer thickness measurements. While THz-TDS has achieved significant success in research environments, the high cost and bulky nature of most ...
