Comparative Analysis of the Impact of CATV Return Path Ingress and Impulse Noises in a 16-QAM Transmission System
نویسنده
چکیده
For the first time, we report the link between, on the one hand, return path ingress and impulse noises measurements and, on the other hand, their relative impact on a 16-QAM transmission. We show that both ingress and impulse noise measurements must be realised in parallel in order to characterise return path noise performance. Diagrams (spectrograms) which exploit both ingress and impulse noises measurements are presented and could help cable operators to select good frequency bands in terms of both ingress and impulse noises.

Some TDMA and OFDM/CDMA receiver structures for communication over the return path of the CATV network
This paper deals with the derivation and comparison of some promising TDMA and OFDM/CDMA receiver structures for communication over the return path channel of the cable TV (CATV) network. Regarding TDMA, it is shown that the performance substantially improves by using equalization. Given the slowly varying, frequency selective nature of the ingress noise, OFDM seems an interesting possible acce...
متن کاملSecrecy of Communications in Data Transmission by Impulses with Unknown Moments of Appearance and Disappearance
We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...
متن کاملImproved Adaptive Median Filter Algorithm for Removing Impulse Noise from Grayscale Images
Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...

There are many unavoidable noise interferences in image acquisition and transmission. To make it better for subsequent processing, the noise in the image should be removed in advance. There are many kinds of image noises, mainly including salt and pepper noise and Gaussian noise. This paper focuses on the research of the Gaussian noise removal. It introduces many wavelet threshold denoising alg...
متن کاملDesign of Out-of-Band Protocols to Transmit UHDTV Contents in the CATV Network
The goal of an UHDTV is to broadcast digital video contents which is 16 times the pixel resolution of HDTV. As the resolution is increased, the UHDTV requires a transmission technology to support very high data transfer rate. In this paper, we propose two out-of-band protocols to transmit UHDTV contents in a CATV network: an OOB-based protocol and a DSG-based protocol. The former may be a short...
