In a cooperative network, relaying nodes transmit to the destination information that is related to the message sent by the source. In literature the performance of such networks is usually studied under the (unrealistic) assumption of perfect …
In this paper, we propose an iterative 'turbo' channel estimation algorithm for known symbol padding (KSP) OFDM, where the guard interval is filled with pilot symbols. Additional pilot symbols are transmitted on some of the OFDM carriers. The channel …
In this paper we present a low-complexity iterative algorithm to estimate the Time of Arrival (ToA) of an Impulse-Radio Ultra Wide Band (IR-UWB) system with pulse overlap between the first two paths. The performance of this SAGE estimation algorithm …
