摘要: | 家用微型基地台(Femtocell)是突破大型基地台在室内有很严重的衰减和覆盖率不佳的问题的解决 方案,为了因应室内的多视点3D 高画质多媒体视讯传输所需要的Gigabits 等级传输速率。发展家 用高速多媒体微型基地台(Multi-Gigabits Multimedia Femtocell)并且兼顾效能、整合与弹性这三大原 则是实作上的一大挑战。 本计画的研究重点有下列几项特点:一、设计高效能多执行绪无线基频处理器(WPU)以提供高运 算处理能力和可重制化(Reconfigurable)的特性;二、使用多输入多输出侦测建立LTE-A based 16 x 16 MIMO-OFDM 平台达成超十亿位元级传输速度的目标,并发展适用之波束成形(Beam-forming) 的技术;三、发展高速传输模式下之对抗射频与通道非理想效应基频演算法及核心同步技术;四、 利用多核心阵列处理器实现高效能无线基频处理器的软体无线电(SDR)以提供基频演算法快速验 证平台。 在三年的计画当中,我们将在第一年度开发LTE-A based 16 x 16 MIMO-OFDM 家用高速多媒体微 型基地台之基频讯号处理器架构和各核心同步技术演算法之设计。第二年度则以多核心阵列处理 器数位讯号处理板实现LTE-A based 16x16 MIMO-OFDM 高效能无线基频处理器的软体无线电验 证平台,进而验证所提出之基频讯号处理演算法的效能。第三年则着重于Corss-layer 系统整合, 并配合其他子计画的规格,对无线基频演算法做硬体与效能上的最佳化,以期能达成整体计画预 期之目标。 A femtocell, which connects to the service provider’s network via broadband such as DSL or cable, is a small cellular base station and typically designed for use in a home or small business. Although the base station has very serious attenuation and poor coverage problems, a femtocell allows service providers to extend service coverage indoors, especially when access points are limited or unavailable in this area. In order to apply the multi-view 3D high-definition multimedia video transmission in indoor, the transmission rate needs increasing to gigabits level. The development of domestic high-speed multimedia base station (Over Gigabits Multimedia Femtocell) has challenge in implementation to obtain the batter performance, higher integration and more flexibility. This research project has the following several characteristics: First, the multi-threaded or multi-core architecture design of wireless baseband processor unit (WPU) can provide high computing ability and reconfiguration characteristics; Second, the multiple-input multiple-output detection block can enhance the performance to obtain the goal of gigabits-level transmission rates in LTE-A based 16 x 16 MIMO-OFDM platform; Third, the new software-defined radio (SDR) verification platform, which use the array processor DSP, can fast evaluate baseband algorithms; Fourth, the development of baseband algorithms and essential synchronization technology against the non-ideal effects of channel or RF in the high-speed transmission mode. Among the three-year plan, we will develop the baseband architecture of LTE-A based 16 x 16 MIMO-OFDM home-used high-speed multimedia femtocell and major synchronization algorithm designs in the first year. Array processor based on digital signal processing board is used to create the LTE-A based 16x16 MIMO-OFDM SDR verification platform, and then verify the performance of proposed baseband signal processing algorithms in the second year. In the third year, we focus on Corss-layer system integration that matches the spec of other sub-plans, and optimize the hardware performance of wireless baseband algorithms to gain the expected goal in the overall system. |
