Due to the strong ability in combating multipath fading, OFDM has been adopted in IEEE802.11a standard and has received considerable attention. The fundamental physical layer parts of OFDM-based IEEE802.11a are modeled and simulated in this paper. Second, we discussed the bit error rate performance of BCH, cyclic and convolutional coding in AWGN channel. Moreover, the system performance of four working...
We built a Simulink PHY Layer platform of OFDM-based IEEE802.11a standard. An improved puncturing method was proposed according to the principle of Viterbi decoding, and we did some simulations and analysis of the link layer properties under different Eb/N0 based on the same parameters of the PHY Layer in IEEE802.11a. We could reach the conclusion of the improved puncturing method increases about...
