In the NextG systems, as we go to the higher data rates, the channels become truly broadband where multipath fading is a major limitation for performance of the wireless transmission if it is not managed[r]

The radio transmissions however are subjected to many constraints which return the narrow band transmission sometimes insufficient. It is the case in particular when the radio wave propagation is effected by multi traffics. The transmission techniques like the spreading[r]

1. What is the key value by defect of the signal 2? What does it mean? For the first part of the tests, we keep the key value of the signal 1 on "10110111000" and the key of the signal 2 on "1". There is thus nothing to modify. 2. (a) Choose a modulation type b[r]

4.2 Transmit antenna selection in MIMO systems
Transmit antenna selection techniques were first proposed during the very late 90s in the context of MIMO links in order to improve the array gain. During that period, antenna selection was derived according to the class of ST coding scheme t[r]

Multivariate analysis is a "mixed bag." It is difficult to establish a classification scheme for multivariate techniques that both is widely accepted and indicates the appropriateness of the techniques. One classification distinguishes techniques de­ signed to study i[r]

Nanocrystalline ceria with high surface area and mesoporosity was prepared by template-assisted precipitation method. The method of preparation was facile, using low-cost reagents and could be performed on a large scale. Cerium oxide support was characterized by Brunauner – Emmett - Teller (BET), X-[r]
