Mediumband Wireless Communication
​​In modern wireless communication systems like 4G, 5G, WiFi, the information bearing signal is a broadband waveform. Using IFFT and FFT blocks at the transmitter and receiver respectively, the broadband waveforms are traditionally designed as a set of parallel narrowband waveforms. However, narrowband waveforms have many drawbacks. Because, their signalling rate is low and are exposed to excessive deep fading.
The research have shown that it is more favourable to make broadband waveforms, not as a set of parallel narrowband waveforms, but as a set of “parallel mediumband waveforms”. Why do these mediumband waveforms matter? It is because, they do signalling at a faster rate, can avoid deep fading and also can afford more interference. Read more about mediumband waveforms below.
