We study the case where a narrowband (NB) signal, intended possibly for an Internet of Things (IoT) application, is concurrently transmitted with a legacy wideband (WB) Wi-Fi signal by means of overlay — meaning that the two signals are not orthogonal to each other. Concurrent operation is particularly seen as a means to achieve high spectral efficiency in… CONTINUE READING
