The EU emergency Call (eCall) system is designed to be used as a vehicle emergency telematics system to reduce the fatality and save lives in vehicle accidents. In-Vehicle System (IVS) is a built-in modem to process the eCall functionality in vehicles. The IVS employs multiple modules for signal processing including cyclic redundancy check (CRC), Turbo Encoder, Hybrid automatic repeat-request (HARQ), BCH Decoder, Modulator and Demodulator. Designing of the IVS modem on a chip requires a lot of challenging and efforts. Field programmable gate array (FPGA) is the state-of-the-art and a modern solution to develop the very large scale integrated circuit (VLSI) of the IVS chip.

This dissertation presents the chip design procedures for the eCall in-vehicle system (IVS) modules. The modules of the IVS transmitter modem are designed as a single chip. Also, a single chip is developed to process the IVS receiver modem. The eCall related works are summarized. The FPGA technology is utilized to develop the IVS modules. Xilinx ISE tool and Verilog HDL are used to develop the register transfer level (RTL) of the designed modules. The developed IVS transmitter and receiver are compiled, synthesized, and simulated. An FPGA device is employed as a hardware solution to implement the developed modems. The employed algorithms and hardware interfaces of the IVS modem are analyzed and discussed. A complete set of the input signals are used to simulate and verify the designed modules. The developed chips are tested and verified for different frequencies. Furthermore, the future works and research plans to develop the IVS modem on a single chip are proposed.
