Cooperative communication is a promising technique that achieves spatial diversity without requiring multiantenna receivers. In this paper we consider the cooperative Amplify-and-Forward protocol and assume the channel realizations to be unknown. We …
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, …
