This paper presents an implementation solution for a digital baseband receiver, which consists mainly of an analog symbol timing recovery (STR) block and a digital carrier recovery block. The STR is realized based on “one-sample-per-symbol” sampling, resulting in relaxed requirement on the A/D converter’s sampling speed. In this sense, the proposed implementation solution is hardware efficient. To...
A novel FPGA-based Differential QPSK modem (modulator and demodulator) is presented for data rates up to 2.5Gbps, in which no DAC or ADC is used. The targeted application is E-Band microwave Point-to-Point radio links in mobile backhaul for LTE and beyond.
