Signal orthogonality
Did you know?
WebIn orthogonal signaling, the choice of x(t) is made from a family of orthogonal functions (which have nice properties for decoding and noise analysis). Let us consider a concrete example that will be explored in detail in the following sections. The sender transmits a waveform x(t) over a period of time T. WebIn vector analysis, a vector with polar coordinates A, φ and Cartesian coordinates x = A cos(φ), y = A sin(φ), can be represented as the sum of orthogonal components: [x, 0] + [0, …

Although CSS can offer high processing gain, its poor spectral efficiency and the lack of orthogonality among different chirps tend to limit its potential. In this paper, we derive the condition to orthogonally multiplex an arbitrary …
WebJan 20, 2024 · 1. Mathematically speaking, orthogonality is derived from a scalar product. For finite dimensional vectors, the scalar product is the inner product as you know it. IN QM the vector spaces we consider are often of infinite dimension. The vectors are represented as functions, and the inner product is an integral. WebOrthogonal Time Frequency Space Modulation Arman Farhang, Ahmad RezazadehReyhani, Linda E. Doyle, and Behrouz Farhang-Boroujeny Abstract—Orthogonal time frequency space (OTFS) modula-tion is a two-dimensional signaling technique that has recently emerged in the literature to tackle the time-varying (TV) wireless channels.
