—Cellular systems of the fourth generation (4G) have been optimized to provide high data rates and reliable coverage to mobile users. Cellular systems of the next generation will face more diverse application requirements: the demand for higher data rates exceeds 4G capabilities; battery-driven communication sensors need ultra-low power consumption; control(More)
Bigger, faster, higher? The appetite for broad-band has clearly fueled the development of mobile cellular networks. On the other hand, the successful deployment of killer applications in the past 20 years has had a major impact on the markets as well: First and foremost, the need for unteth-ered telephony and, with it, wireless real-time voice communication(More)
—Generalized frequency division multiplexing (GFDM) is a new concept that can be seen as a generalization of traditional OFDM. The scheme is based on the filtered multi-carrier approach and can offer an increased flexibility, which will play a significant role in future cellular applications. In this paper we present the benefits of the pulse shaped(More)
—This work presents a synchronization approach using an embedded training sequence in the payload of a Generalized Frequency Division Multiplexing (GFDM) symbol. The proposal explores the pulse-shaped subsymbol structure of GFDM to design a midamble. Autocorrelation, correlation and false alarm threshold criterion are the tools used for estimation of(More)
— LTE and LTE-Advanced have been optimized to deliver high bandwidth pipes to wireless users. The transport mechanisms have been tailored to maximize single cell performance by enforcing strict synchronism and orthogonality within a single cell and within a single contiguous frequency band. Various emerging trends reveal major shortcomings of those design(More)
—Generalized frequency division multiplexing (GFDM) is a multi-carrier modulation scheme. In contrast to the traditional orthogonal frequency division multiplexing (OFDM), it can benefit from transmitting multiple symbols per sub-carrier. GFDM targets block based transmission which is enabled by circular pulse shaping of the individual sub-carriers. In this(More)
Generalized frequency division multiplexing (GFDM) is a block filtered multicarrier modulation scheme recently proposed for future wireless communication systems. It generalizes the concept of orthogonal frequency division multiplexing (OFDM), featuring multiple circularly pulse-shaped subsymbols per subcarrier. This paper presents an algorithm for GFDM(More)
