—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)
— 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)
Most of hybrid motion compensated video coding standards uses a well known discrete cosine transform (DCT) at the encoder to remove redundancy from video random processes. Due to the huge number of computations required to compute the DCT, reduction of its complexity is essential to speed up video processing. To optimize the computation of the DCT, we take(More)
—This paper provides intermediate transceiver and frame structure concepts and corresponding results for the European FP7 research project 5GNOW. The Unified Frame Structure concept is presented which supports an integrated 5G air interface, capable of dealing both with broadband data services and small packet services within the same band. Waveforms which(More)
