| Abstract: | The problem of training symbol placement and power for the channel estimation of OFDM over block-fading channel in the presence of null subcarriers is considered. We use convex optimization techniques to find a pilot design that results in near-optimal channel estimation. We design OFDM preamble and then, based on the obtained preambles, we design pilot symbols and their placements for pilot aided channel estimation using our proposed iterative algorithm. Several examples based on the IEEE 802.16 are provided to demonstrate the efficacy of our proposal. |
