Digital RF Processor (DRP™)
Published in Krzysztof Iniewski, Wireless Technologies, 2017
Of a special note is measured RX sensitivity of −82 dBm for Bluetooth and −110 dBm for GSM, versus the respective specifications of −70 dBm and −102 dBm—it is among the best in class. The overall GSM RX noise figure is only 2 dB. TX performance is also excellent. Figure 10.3 shows that the modulated GSM spectrum has 8 dB of margin at the most critical frequency offset of 400 kHz. The margin is even greater with EDGE (8 phase shift keying [8PSK]) modulation scheme, as shown in Figure 10.4. The measured error vector magnitude (EVM) is 1.24%.

In 2021 Mallick, K., et al [13] suggested bi-OFDM-based MMWOF and THzWOF systems to test MMW and THzW in the context of a 5G access fronthaul network. L and C b, as well as Q dash LD, serve as bandwidth for downlink and uplink transmission, generating MMW and THzW beat frequencies, respectively. Due to its low bit rate of errors, tolerable error vector magnitude (10.2%), and clear constellation diagram, it has improved the system’s capabilities.

Error vector magnitude (EVM) can be derived from the constellation diagram by estimating the difference between the ideal constellation point to the actual constellation points (2) (http://www.rfwireless-world.com/Terminology/Error-Vector-Magnitude.html).
