The paper investigates both block-type pilot linear minimum mean square error algorithm and IEEE802.16 OFDM channel estimation analysis. Simulation results confirm the block-type pilot structure is more suitable for IEEE802.16 system. An optimal pilot setting algorithm, based on space frequency domain, is explored and the pilot chart is presented. The proposed algorithm finds its application in MIMO-OFDM. Simulation results show the algorithm presents a good approximation to the perfect channel state information curve, with about 2dB difference in SNR. The simulation results also demonstrate the algorithm achieves fairly high stability in the environment of fast fading, performance of the proposed algorithm is better that of pilot training channel estimation.3. Taking into account the characteristics of IEEE802.16 OFDM system, OFDM system simulation platform is constructed in Matlab, exploiting simulink as a tool. OFDM modulation and demodulation simulation system are configured on LabVIEW platform. All the system signal processing is simulated, including defining system parameters, designing modulation model, and verifying all the proposed algorithms under different environments, such as white Gaussian noise, multi-path fading, with or without guard interval etc. Bit error performance is evaluated. The research provides valid theoretical basis for practical OFDM system performance evaluation.4. Taking advantage of software radio, the paper designs a hardware platform with both 256-IFFT/FFT and 512-IFFT/FFT OFDM schemes co-existing in one platform. You can predetermine one from the two schemes to carry out almost the same model function with different system performance and parameter setting.5. Referring to IEEE802.16 standard, the paper proposes a design method for generating signals and frames suitable for laboratory investigations implemented in laboratory environment.6. Based on 6701evm digital evaluation card, combined with analogy front-end, the paper designs a DSP software model to deal with baseband signal processing. An overall OFDM scheme, with modulation and demodulation function, is accomplished.

If it be contended in the case of the former passage that the sleep of the soul so effectually erases the interval between death and resurrection that the prospect of being with Christ, even though actually long delayed, could produce joyful anticipation, in any event the same thing can hardly be said for the second passage, where not only the resurrection body but the intermediate state is directly contemplated, being a less desirable alternative than the change to the resurrection body without death vs.

如果它在有争议的情况下，前一段睡眠的灵魂，所以有效地除去间隔死亡和复活认为前景正在与基督，即使实际上是拖延已久的，能产生愉悦的期盼，在任何情况相同事很难说，为第二次通过，那里不仅复活体，但中间状态，是直接的争议，作为一个较理想的办法比的变化，以复活的身体没有死亡（比4）。

Exibility for point sampling. Secondly, by combining the splat-ting algorithm with Layered Depth Buffers, we implement an algorithm fordetermining the points'visibilities and re?ectance properties, which is more accuratethan pervious methods.
