The cost that this graph is mobile phone hardware follows the comparison of cost of software of mobile phone platform, everybody can see mobile phone cost or pretty are tall 2003, mobile phone operating system holds the cost of 10% whole mobile phones at that time, but come down a few years, the hardware price of mobile phone platform is to go down, dropping every year downward, the likelihood still is in surely over there by the price of software, occupy the dimensions of 10% to grow to be occupied this year only from before 25%, so this to a lot of users, I believe to any user it is very big expense, why mobile phone platform cannot quite free, why cannot fall this price lowlier quite, let more user enjoy the service of Internet, this is the platform that Gu Ge follows a lot of companies to roll out Andrord together, a moment ago David Axmark had said the benefit that opens a source.

这个图是手机硬件的成本跟手机平台软件成本的比较，大家可以看到2003年手机成本还是蛮高的，那个时候手机操作系统占到10%整个手机的成本，可是几年下来，手机平台的硬件价格是下去了，每年都在往下掉，可能受到软件的价格还是定在那里，从原来只占10%的规模成长到今年占到25%，所以这一点对于很多用户，我相信对于任何一个用户都是很大的开销，为什么手机平台不能够免费，为什么不能够把这个价格降得更低，让更多用户享受到互联网的服务，这个就是谷歌跟很多公司一起推出Andrord的平台，开源的好处刚才David Axmark已经讲了。

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.
