Q-Learning Based Scheduling With Successive Interference Cancellation

Power control for successive interference cancellation with imperfect cancellation

This paper proposes and analyzes an iterative power control scheme for use with successive interference cancellation (SIC) in the presence of cancellation errors. In [1], SIC is shown to increase the capacity of cellular CDMA systems significantly, even if the signal cancellation is imperfect due to estimation errors. However, an important complication of SIC relative to conventional CDMA recei...

Successive Interference Cancellation Based Signal Detector for Wireless MIMO Communications

Successive Interference Cancellation for MIMO UW-OFDM

Unique word orthogonal frequency division multiplexing (UW-OFDM) is a new signaling concept which has better spectral properties and also a superior bit error ratio (BER) performance over conventional cyclic prefix (CP) based OFDM. In UW-OFDM, the CPs are replaced by deterministic sequences, the so-called unique words (UWs). So far, the performance of UW-OFDM has been well investigated for sing...

Successive Interference Cancellation in Heterogeneous Cellular Networks

At present, operators address the explosive growth of mobile data demand by densification of the cellular network so as to reduce the transmitter-receiver distance and to achieve higher spectral efficiency. Due to such network densification and the intense proliferation of wireless devices, modern wireless networks are interference-limited, which motivates the use of interference mitigation and...

Scheduling on uplink of CDMA packet data network with successive interference cancellation

Uplink scheduling in wireless systems is gaining importance due to arising uplink intensive data services (ftp, image uploads etc.), which could be hampered by the currently in-built asymmetry in favor of the downlink. In prior work [1], [2], we proposed optimal algorithms for uplink scheduling in a CDMA cell that does not employ any form of interference cancellation. In this work, we modify th...
