摘要: | MIMO-OFDM 多天线无线系统中,兼顾效能与功耗是设计上的关键。因此在符合这 两大原则之下,必须以系统考量来达到降低功耗并兼顾性能的提升。由于许多国际单位 已开始制定高传输速率标准规范,因此如何能够发展新规范的8x8 MIMO-OFDM 系统, 达成高传输速率并参与国际标准制定为一大挑战,而其中提升同步上的效能以及降低通 道的影响将对MIMO-OFDM 基频处理器的效能是非常关键的因素。 本研究计划的重点,主要考量如何发展 8x8 MIMO-OFDM 基频接收器中之同步处理 的正确性、抗脉冲干扰及通道补偿演算法,在系统考量之下探讨同步区块操作在静止或 移动模式之下的特性,以瞭解移动效应对整个8x8 MIMO-OFDM 系统及讯号有何影响, 发展所需的低功耗关键技术,建立8x8 MIMO-OFDM 无线平台- 以参数化为设计考 量,把关键技术以IP 的方式实现,并完成无线验证。其目的在于增进系统性能、缩短 研发时程、降低设计复杂度并参与国际标准制定。 Low power, robustness and high data rate are the key issues in MIMO-OFDM systems and related applications, such as e-Home, and Next-Generation WLAN/UWB …etc. In order to promote new wireless standards about power, rate, cost and turnaround efficiency, the top-down design methodology must use to optimize system specifications. As a result, it is important for 8x8 MIMO baseband to develop a suitable system and to build a related platform before standard meeting, that a suitable platform can be used to determine proper parameters and to prevent try-and-error and to verify system as well. From the viewpoints of system realization, it will be more efficient to make key techniques/modules as IPs. In this 3-year research project, a design platform will be investigated and explored for 8x8 MIMO-OFDM baseband, first. Based on this platform, the kernel IPs and synchronization techniques, such as anti-impulse jamming, adaptive equalizer, packet acquisition, timing/frequency synchronizations and so on, will be developed to realize an available system. In summary, this research project focuses on the novel 8x8 MIMO wireless baseband, related IPs techniques and complete design platform to promote our specifications in wireless standards. |
