Single-Carrier FDMA or Cyclic-Prefix CDMA With Optimized Spreading Sequences?

Performance of Cyclic Prefix Assisted Single Carrier CDMA Uplink System with MIMO Multiplexing

In this paper, we describe a novel type of cyclic prefix assisted single carrier CDMA system with Frequency Domain Equalization (FDE) and MIMO Multiplexing. The proposed method is referred to as MIMO SC/FDE CDMA. Multipath Interference can be mitigated by inserting cyclic prefix at the transmitter. Furthermore, we use different scrambling codes to separate different transmit antennas. At the re...

Frequency Domain Interference Cancellation for Single Carrier Cyclic Prefix Cdma Systems

In this paper, we propose a low complexity receiver structure for Single-input Multiple-output (SIMO) downlink cyclic prefix CDMA (CP-CDMA) systems. It employs an interference cancellation scheme to suppress the interference caused by the multipath fading channel. Also, the proposed scheme is developed for Multiple-input Multiple-output (MIMO) CP-CDMA system. All filters in the proposed receive...

A Subtractive Interference Cancellation Scheme for Single Carrier Block Transmission with Insufficient Cyclic Prefix

We propose a simple inter-symbol interference (ISI) and inter-block interference (IBI) cancellation scheme for single carrier block transmission with cyclic prefix (SCCP) systems with insufficient guard interval (GI). In the SC-CP system, the equalization and demodulation processing is conducted in a block-by-block manner, therefore, the IBI can be reduced by using previously detected data sign...
