Spectrum sensing is one of key technologies in cognitive radio to obtain radio environment knowledge. However, the regular correlator detector suffers from the inference of multipath fading channel on the primary signal. In this paper we propose a theoretically simple, yet effective and implementation-friendly spectrum sensing scheme called multi-peak values (MPV) detector. Based on the criterion...
The long term evolution of UMTS Terrestrial Radio Access (UTRA LTE) and its enhanced version - LTE-Advanced use OFDM (orthogonal frequency division multiplexing) combined with MIMO (multiple-input multiple-output), termed MIMO-OFDM. The spatial multiplexing (SM) MIMO scheme is deployed in LTE and LTE-Advanced downlink to provide high data rates. In this communication, the authors will discuss a set...
Recently, the LTE (Long Term Evolution) and LTE-Advanced systems, developed by the 3GPP (Third Generation Partnership Project), has been proposed as the candidate for the 4G systems (forth mobile communication systems). The combination of OFDM (orthogonal frequency division multiplexing) and MIMO (multiple-input multiple-output) transmission technologies has been introduced into LTE systems for achieving...
The 3GPP (Third Generation Partnership Project) LTE (Long Term Evolution) and LTE-Advanced activities work toward the evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access (E-UTRA), and the solution of IMT-Advanced (International Mobile Telecommunications) and systems beyond. The combination of OFDM (orthogonal frequency division multiplexing) and MIMO (multiple-input...
