Description
本發明有關於一種多天線量測系統,且特別是一種應用於多重路徑環境下的多天線電子裝置開發系統。 The present invention relates to a multi-antenna measurement system, and more particularly to a multi-antenna electronic device development system for use in a multipath environment.
無線通訊產品在多重路徑應用環境下使用場景多,被動天線已無法滿足實際需求,天線需要能因應使用場景,例如:各種人體靠近方式、戶外/室內、都會/鄉村或水泥/木頭建築環境。然而,就實際產品而言,產品外型(輕薄短小)限制了天線設計想法,天線需內建甚至隱藏於產品中,天線輻射體常必須與產品其他功能之金屬共用,天線輻射性能因應各個專案不同,難以形成標準,當然無線晶片因成本因素也無法不斷客製演算法配合產品使用,使得智能天線設計概念一直無法順利推廣。 Wireless communication products use many scenes in multi-path application environments. Passive antennas can no longer meet actual needs. Antennas need to be able to respond to scenarios such as various human proximity methods, outdoor/indoor, metro/rural or cement/wood construction environments. However, in terms of actual products, the appearance of the product (light and thin) limits the idea of antenna design. The antenna needs to be built in or even hidden in the product. The antenna radiator must always be shared with the metal of other functions of the product. The antenna radiation performance is suitable for each project. Different, it is difficult to form a standard. Of course, the wireless chip cannot be continuously used by the algorithm and the product due to the cost factor, so the smart antenna design concept has not been smoothly promoted.
傳統智能天線設計方式是由無線晶片開發公司主導,無線晶片用於比較各(組)天線收訊狀況,再選擇最佳天線組合,在視線(Light-Of-Sight,LOS)條件下若訊號穩定,這方式較有實現的可能性。然而,在多重路徑的應用場景下,收訊狀況並不穩定,使用訊號比較法所達到的效能難以進一步提升。 The traditional smart antenna design method is led by the wireless chip development company. The wireless chip is used to compare the reception status of each (group) antenna, and then select the best antenna combination. If the signal is stable under the condition of Light-Of-Sight (LOS) This method is more likely to be realized. However, in the multi-path application scenario, the reception status is not stable, and the performance achieved by the signal comparison method is difficult to further improve.
相對而言,如果要以天線設計層面來主導智能天線 設計或者多輸入多輸出(Multi-Input & Multi-Output,MIMO)天線系統,除非無線晶片商願意開放晶片藉由天線收到的所有環境應用訊息,否則天線設計者無法針對天線做控制或選擇。無線晶片開發成本及時間長,在未確認新的智能天線設計或多輸入多輸出天線方案確實可行的條件下,貿然投入晶片開發的風險過高。 In contrast, if you want to dominate the smart antenna design or Multi-Input & Multi-Output (MIMO) antenna system with the antenna design level, unless the wireless chip vendor is willing to open all the environmental applications received by the antenna through the antenna. Message, otherwise the antenna designer cannot control or select the antenna. Wireless chip development costs and long time, the risk of rushing into wafer development is too high without confirming that the new smart antenna design or multi-input multi-output antenna scheme is feasible.
本發明實施例提供一種應用於多重路徑環境下的多天線電子裝置開發系統,對使用多輸入多輸出(MIMO)天線系統的多天線電子裝置進行空中傳輸(Over The Air,OTA)的環境參數量測,可取代傳統上對於天線元件特性僅使用網路分析儀(Network Analyzer,NA)的量測方式。 Embodiments of the present invention provide a multi-antenna electronic device development system applied in a multi-path environment, and an environmental parameter quantity of over-the-air (OTA) for a multi-antenna electronic device using a multiple input multiple output (MIMO) antenna system The measurement can replace the traditional measurement method using only the Network Analyzer (NA) for the antenna element characteristics.

The multi-antenna module has a plurality of antenna units, each antenna unit having at least one antenna element and at least one RF switch, the RF switch being connected and controlled by the switching controller. The wireless transmitter is configured to transmit a non-signaling wireless signal to a plurality of antenna elements of the multi-antenna module using a multiple input multiple output (MIMO) transmission mode.

綜上所述,有別於傳統的天線量測系統需要先對天線完成天線基本參數量測(視線條件,通常必要在電波暗室完成量測),然後再結合無線晶片整機(產品)量測,本發明實施例提供應用於多重路徑環境下的多天線電子裝置開發系統能夠在電子裝置所使用的無線通信標準已決定但無線晶片尚未開發完成時,預先針對無線晶片所使用的多天線效能進行非信令(non-signaling)量測、設計與效能評估,直接獲得對於無線晶片更具參考價值的多天線效能。當本發明實施例的此開發系統完成多天線的量測後,研發人員將使用無線晶片做信令(signaling)量測的結果與本發明實施例的此開發系統的量測結果做比較時,即可更直覺地、快速地分辨出無線晶片(控制及處理端)與多天線(接收端)兩者整合後的問題。簡言之,本發明實施例的此開發系統是整合了無線系統設計與天線設計兩者需求的多天線電子裝置開發系統,具體地明晰了多輸入多輸出的多天線特性的數據對於無線晶片的可參考價值,大幅度地提升產業界的無線系統設計研發人員與天線設計研發人員兩方對於多天線無線信號接收端的多天線電子裝置的開發效能,諸如縮短產品開發時間、快速解決研發過程所發生的問題、決定影響無線通信性能問題的歸屬(判斷問題是源自於無線晶片或是歸因於天線性能不佳)等。 In summary, unlike the traditional antenna measurement system, it is necessary to complete the basic parameter measurement of the antenna (the line of sight condition, usually necessary to complete the measurement in the anechoic chamber), and then combine the wireless chip machine (product) measurement. The embodiment of the present invention provides a multi-antenna electronic device development system applied in a multi-path environment.
