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.

Fill a tulip-shaped glass with red wine to one third of a full glass (5cm from the foot of the bottom).Observe the wine. Lean 45 degrees to check its color against a white background. Fine dry red wine looks clear and glossy. By observing the color and tone of the wine, you coukd make good judgment about its maturity. Usually the deeper in yellow tone it looks, the more aged the wine is; the paler in color or deeper in purple tone it looks, the less aged the wine is.Smell the wine. Gently shake the glass for better contact between wine and air until the aroma of the wine evaporates enough. Reach your nose into the glass, smell gently and quickly. Fine red wine is rich in aroma, dense and subtle, with both the aroma from grape and the matching oak fragrance.Taste the wine. Take a deep sip, simultaneously draw in the air over the wine, whirl the wine inside every part of your mouth, fully appreciate its flavor before swallowing. Sense the aftertaste and make a good judgment of its potential quality.

试酒 首先，将红酒倒入郁金香型杯中，倒至酒杯的三分之一处（距杯角约5厘米处）即可，倾斜45度，对着白色的背景看颜色，好的干红葡萄酒应该是清澈、有光泽，根据葡萄酒颜色的深浅及色调，也可以判断出红酒的成熟度，同常红葡萄酒颜色越深、黄色调越重酒越老，颜色越浅、紫色调越重酒越年轻；闻香味，酒杯轻轻晃动，促使酒与空气接触，使酒的香气释放出来，然后将鼻探入杯中，短促的轻闻，红葡萄酒香味丰富、浓烈而复杂，既有葡萄本身所发出的果香，又有因在橡木桶中醇化而产生的丰富和谐的橡木香；然后品尝味道，深啜一口，同时吸入酒上方的空气，并让酒在口中打转，使之到达口腔的每一个部位，充分品尝它的味道，最后将酒下咽，同时感觉酒下咽喉后留在口中的滋味，体会它的余韵以判断酒是否有潜质。
