Code-aided ML joint synchronization and channel estimation for downlink MC-CDMA
Abstract--In this paper, we present a novel code-aided joint synchronization and channel estimation algorithm for downlink multicarrier code-division multiple access. The expectati...

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...

Adaptive Interleaving for OFDM in TDD Systems
We proposed a novel interleaving technique, namely ada,ptive interleaving, which can break the bursty channel errors more effectively than traditional block interleaving. This new...

Channel Capacity Estimation using Free Probability Theory
—In many channel measurement applications, one needs to estimate some characteristics of the channels based on a limited set of measurements. This is mainly due to the highly tim...
