  1. Capacity series and radio - frequency channel arrangement for analog microwave relay systems

    模擬微波接立通信系統容量系列及波道配置
  2. Growing demand for greater wireless data capacity and the crowding of regulated radio - frequency spectra favor systems that offer not only high bit rates but high bit rates concentrated in smaller physical areas, a metric that has come to be called spatial capacity

    由於人們不斷要求更大的無線資料容量，再加上受管制的無線電頻譜已趨飽和，受到青睞的系統不僅要能提供高位元速率，而且必須集中在較小實體區域內，這樣的衡量標準稱為空間容量。
  3. Capacity series and radio - frequency channel arrangement and equipment main technical specifications for 100 1000mhz radio relay communication systems

    100 1000mhz接力通信系統的容量系列波道配置及設備的主要技術要求
  4. Space - time coding technology is based on multi - elements antenna array and has strong points of both time processing and space processing. it can satisfy the requirements of high data rate transmission in the future radio mobile system without the increase of the transmitting power and the spread of the frequency. and it can greatly improve the quality of communication services and system capacity under fading channels

    空時編碼技術是一種利用多天線陣發送和接收的技術，該技術能很好地結合時間處理技術和空間處理技術的特點，能在不增大發射功率和不擴展頻帶的前提下滿足未來無線移動通信對高數據率傳輸的要求，從而全面提高衰落通道的通信質量和通信系統容量。
  5. Fortunately, a novel creative technology, namely multiple - input multiple - output ( mimo ), has provided an innovative solution to this problem. mimo technology utilizes multiple antennas at both transmit and receive ends of the radio link to multiply the capacity and reliability by fully exploiting the space resource within the same frequency band at no additional power expenditure

    可幸的是，多入多出（ mimo ）無線通信技術為解決該問題提供了全新的途徑，它在無線鏈路收發兩端均採用多天線，充分開發空間資源，在無需增加頻譜資源和發射功率的情況下，成倍地提升了通信系統的容量與可靠性。
