FlexRay is a new standard for network communication systems, which has been developed for future automotive applications. FlexRay communication controller (CC) is the core of the FlexRay protocol specification. Bus guardian (BG) is an optional electronic component. In this paper, we first design the FlexRay CC and BG protocol specifications and function modules using specification and description language (SDL). Then, the system is implemented using Verilog HDL based on the SDL source. The FlexRay design is synthesised using Samsung 0.35 μm technology and the operating frequency is above 76 MHz. To validate our designed FlexRay system, it is combined with sound source localisation system in robotics applications. The integrated system is implemented using ALTERA Excalibur ARM EPXA4F672C3. The system operates successfully as demonstrated in experimentation.

Squaring is an important operation in many algorithms. In this paper, an efficient design approach for the combined squarer, capable of operating on either unsigned or twos complement numbers based on a mode selection signal, is presented. By simulations, it is shown that the proposed combined squarers lead to up to 17% reduction in area, 10% reduction in propagation delay and 9% reduction in power consumption compared with the previous combined squarers.

Different detection technique approach in wireless communication for multi input multi output (MIMO) systems at last ten decades. Lattice reduction aided detectors are also use extensively in MIMO systems. These detectors are introduce and work on the traditional algorithm which was originally base on reducing real lattice bases. In this paper, we use complex lattice reduction processing in dual basis to reduce channel matrix and compare the parameters that affect the complexity of the LLL algorithm for MIMO detection. Through use of the complex lattice reduction in Dual basis, the performances of bit error rate are much improved at 8 8 × MIMO system.
