A Novel Graph-Based Suboptimal Multiuser Detector for FDM-CPM Transmissions
We consider a frequency division multiplexed (FDM) system where each user employs a continuous phase modulation (CPM), serially concatenated with an outer code through an interleav...

MC-CDMA Based IEEE 802.11 Wireless LAN
In this paper, a modified version of the IEEE 802.11a protocol is proposed and evaluated. We combine MultiCarrier Code Division Multiple Access (MC-CDMA), a novel, high capacity m...

Sparsity-Aware Estimation of CDMA System Parameters
The number of active users, their timing offsets, and their (possibly dispersive) channels with the access point are decisive parameters for wireless code division multiple access...

Sphere Decoder for a MIMO Multi-User MC-CDMA Uplink in Time-Varying Channels
— We focus on iterative detection for the uplink of a multi-carrier (MC) code division multiple access (CDMA) system based on orthogonal frequency division multiplexing (OFDM). T...

Channel Prediction Aided Multiuser Transmission in SDMA
— Transmit preprocessing employed at the basestation (BS) has been proposed for simplifying the design of the mobile receiver. Provided that the channel impulse response (CIR) of...
