Alamouti code[1]

Description

The simplest OSTBC, with two time slots, two channels, and with unitary coding matrix \begin{align} \begin{pmatrix}c_{1} & c_{2}\\ -c_{2}^{\star} & c_{1}^{\star} \end{pmatrix}~, \tag*{(1)}\end{align} where \(c_i\) are complex numbers.

Rate

The only OSTBC with unity rate.

Realizations

Wireless standards since: 3G, LTE, LTE-Advanced, and 5G.WiFi standards: 802.11n, 802.11ad, 802.11ay, etc.
