In an uncoordinated network, the link-level performance of a wireless receiver might degrade significantly due to the interference from other transmitters that share the same spectrum. As a solution, in this study, the concept of partially overlapping tones (POT) is introduced. In POT, interference energy observed at a victim receiver is mitigated by partially overlapping the individual subcarriers...
Future wireless communications should be designed efficiently to support multi-mode operations for different types of applications, such as machine-to-machine, video streaming, web browsing and voice. In the physical layer multi-mode operation could include the coexistence of single carrier and multicarrier modulations. To reduce overall complexity and power consumption, it is highly desirable to...
Dynamic spectrum sharing is a key technique to meet the high data rate demands of future wireless systems evolving towards heterogeneous networks. To make the best use of available frequency resources without creating interference to neighbor nodes, spectrally contained and scalable waveforms are needed. While OFDM has become the most popular multicarrier modulation (MCM) scheme, it suffers from high...
In this paper we describe and simulate an accurate Bit Error Rate (BER) estimator for a chip level Wiener equalizer and combined equalizer/interference canceller for employment with the CDMA MIMO High Speed Downlink Packet Access (HSDPA) feature of the Third Generation Partnership Project (3GPP). In the 2 × 2 MIMO system two data streams may be transmitted in the downlink to each user equipment (UE)...
