Unique-word (UW) OFDM is a new multicarrier technique that was recently proposed in [1]. To construct the UW-OFDM signal, some carriers must be sacrificed to transmit redundant information – these carriers are called the redundant carriers. It turns …
In this contribution, we propose a new code-aided synchronization and channel estimation algorithm for uplink MC-CDMA. The space alternating generalized expectation-maximization (SAGE) algorithm is used to estimate the channel impulse responses, …
This contribution deals with the carrier frequency offset estimation for a flat-fading Multiple-Input Multiple-output (MIMO) channel using a training sequence. The resulting Maximum Likelihood (ML) estimation entails solving a maximization problem …
