Lecture Notes 11: Direct-Sequence Spread-Spectrum Modulation In this lecture we consider direct-sequence spread-spectrum systems. Unlike frequency-hopping, a direct-sequence signal occupies the entire bandwidth continuously. The signal is obtained by starting with a narrowban

Creating Orthogonal Array. As we will explain shortly, the technique proposed in this paper usually requires dif-ferent orthogonal arrays for di erent problems. e con-struction of orthogonal array is not a trivial task since we do not know whether an orthogonal array of given size exists. Many

Orthogonal architecture solutions eliminate long, complex traces, via stub effects, simplify signal links and reduce backplane layer count.

Orthogonal regions are a relatively expensive mechanism1 that the current implementation of the QEP event processor does not support. Also, orthogonal regions aren't often the desired solution because they offer little opportunity for reuse. You cannot reuse the

the traditional orthogonal multiple access (OMA) technology. In order to improve user throughput of OMA, user equipments (UEs) of non-orthogonal transmission technology needs to enhance their receivers with interference cancellation capability in order to elim-inate interferences generated by other users. In this thesis, two kinds of non-orthogonal

More specifically, considering that two signals s 1(t) and s 2(t), which are orthogonal either in

2.2 Basics of Spectrum sensing and Optimization By the spectrum sensing, the CR user is able to find temporally idle spectrum, which is known as spectrum hole or white space. If the licensed user comes active for communication then CR user has to use another spectrum holes or change its transmission parameter to avoid interference.

In the Taguchi design, the array is orthogonal, which means the design is balanced so
