1. 1. Digital Front End Algorithms for Sub-Band Full Duplex

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

   Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

5. 4. Time Synchronization for Full-Duplex Communications

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ziyu Liu; Aamer Al-Hamwi; [2019]
   Keywords : Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

   Abstract : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. READ MORE

6. 5. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE
