This paper presents a novel micro-architecture for high-performance and low-power DSPs. The underlying Synchronous Transfer Architecture (STA) fills the gap between SIMD-DSPs and coarse-grain reconfigurable hardware. STA processors are modeled using a common machine description suitable for both compiler and core generator. The core generator is able to(More)

Most current development strategies for future mobile systems are concerned with partial solutions only regarding the mobility-bit rate problem. In this paper the basic ideas of the Integrated Broadband Mobile System (IBMS), supporting in a unified way a variety of communication classes ranging from high mobility with low data rates towards(More)
Space-time receivers for wireless communication systems offer the possibility to have both TX-and RX-antennas. For a realistic simulation of such systems, a multiple input multiple output (MIMO) spatial channel model is required which reasonably characterizes the space-and time-variant effects of the mobile radio channel. This paper describes a space-time(More)
This paper presents an adaptation of the list scheduling algorithm to generate code for processors of the Synchronous Transfer Architecture (STA) by applying techniques known from RISC and TTA. The proposed scheduling approach is based on informed, deterministic algorithms that can be implemented run-time efficiently. Although the presented compiler(More)
Visual activity governs the functional maturation of the mammalian visual cortex. We report here, that visual experience is required for stabilizing the phenotype of a subset of cortical interneurons. Neurons expressing neuropeptide Y mRNA (NPY neurons) display a transiently higher expression in the early postnatal visual areas 18a and 17 that is followed(More)

IBMS is a concept for future mobile communication systems to provide a large range of data rates with different degrees of mobility. The integration of heterogeneous services and communication systems requires a common Network Access and Connectivity CHannel (NACCH) for basic signaling to provide permanent network access. Smart Antennas are utilized to(More)
— The capacity of Multiple Input Multiple Output (MIMO) communication systems depends on the spatial properties of the MIMO-channel. This work shows how in particular partial correlation of channel coefficients affects the capacity of the system. For partially correlated channel coefficients the performance of such systems can be further be enhanced by the(More)
The purpose of this paper is to determine the possible capacity increase in single hop relay networks , where mobile stations are enabled to serve as additional access points for other terminals. The total power used for direct transmission from a central base station to uniformly distributed mobiles is compared with indirect transmission using mobiles as(More)

1 Abstract Space-Time-Blockcodes (STBC), that have been introduced by Alamouti [1] and Tarokh et.al. [2], are now considered in the current 3GPP standard as one method to achieve spatial diversity. While the performance of space-time blockcodes has been subject of extensive research [3, 4, 2], the impact of channel estimation errors and closed loop power(More)
