Implementing WMAN Using VLSI Design

In this paper we present SISO based decoding scheme for turbo codes using bi-directional SOVA algorithm. The entire implementation has been analyzed in order to suite the IEEE 802.16e, the mobile WiMAX standard. For wireless communication this scheme can be implemented using orthogonal frequency division multiplexing (OFDM) which is a wideband technology designed to eliminate inter symbol interference (ISI) over the multi path fading channel by dividing the whole bandwidth into smaller parallel sub bands and consequently increasing the symbol duration.
