摘要

行動裝置無縫連結的需求與日俱增，是無線通訊產業不斷創新的動力，整合通訊、計算、全球定位系統等功能是今天無線通訊一個不可抵抗的趨勢。系統製造商對於整合多個通訊標準於單一設計平台的要求日益迫切。這些多模平台必需滿足尺寸小、方便攜帶又省電，而且訊號採用不同頻帶、不同調變，佔據的頻寬也不同。迅速整合各自獨立的技術，造就今天日益增強複雜性的無線通訊。本文研究包含GSM四頻(850MHz、900MHz、1800MHz、1900MHz)、WCDMA三頻(Band I、II、V 分別是850MHz、1900MHz、2100MHz)、WiFi、Bluetooth和GPS的多頻多模筆記型電腦、PDA 手機、3.5G HSDPA USB 無線網卡之干擾偵測，並提出解決方案，以滿足省電、低成本、小體積等需求，並符合通訊規範。

The seamless connection demand grows with each passing day to the wireless mobile device, and it is the motive force that the wireless communication industry is innovating constantly. It is a trend that can't be resisted of wireless communication today to combine functions such as the communication、calculation、global positioning system, etc..in a system. That systematic manufacturers try to combine the requirement in the single design platform of a lot of communication standards become urgently day by day. These model's platforms must meet size、easy carry and save the electricity, and the signal adopts different frequency bands, with different modulation method, the bandwidth that occupied are also different. Combine independent technology rapidly, bring up, strengthen complicate wireless communication day by day today. The examples that this text puts forward are GSM four Bands(850MHz、 900MHz、1800MHz、1900MHz), WCDMA three Bands is 850MHz, 1900MHz, 2100MHz separately (Band I、II、V)、WiFi、Bluetooth and GPS in wireless mobile device such as Notebook、PDA phone and 3.5G HSDPA USB dongle . The text focus on EMI detection and solution. Power saving, low cost and small volume will be satisfied to meet communication standard specification.
