Design and implementation of encoding techniques for wireless applications

Dedicated Short Range Communication is a simplex or duplex short range to medium range wireless communication. It is used to support Intelligent Transport System (ITS) applications such as electronic toll collection, parking lot, border crossing identification etc. To achieve dc balance, enhancing signal reliability, FMO and Manchester codes are used in DSRC standards. The usage of different coding techniques leads to limit the design of VLSI architecture of FMO and Manchester coding. This limitation can be conquered by Similarity-Oriented Logic Simplification (SOLS) has proposed in this paper. The Hardware Utilization Rate of FMO and Manchester encoding were increased from 57.14% to 100% using SOLS technique. The performance of this VLSI Architecture is evaluated on cadence-post layout simulation tool with 180 nm CMOS technology. The Manchester codes consumes maximum operation frequency is 2GHz with 1.58 mW power consumption and 900 MHz for FMO coding with 1.14 mW power consumption. The DSRC standards with FMO and Manchester encoding can support America, Europe, and Japan. This paper also shown that area compaction of proposed VLSI architecture compared to existing method.
