【摘要】 本文比较了非对称全数字多波束阵列与混合多波束阵列在系统效能上的表现。从计算结果中看出,对于数据流数为4、子阵单元数为128的典型商用毫米波混合多波束阵列,当毫米波非对称全数字多波束的发射数据流数大于63(射频发射单元数为128)或者发射数据流数大于77(射频发射单元数为256)时,毫米波非对称全数字多波束阵列较商用毫米波混合多波束阵列在系统效能上有优势。当毫米波非对称全数字多波束的接收数据流数大于17(射频接收单元数为64)或者接收数据流数大于23(射频接收单元数为128)时有同样的结论。更多还原

【Abstract】 The system energy efficiency of the asymmetrical full-digital multibeam array(AFDMA) and of the hybrid multibeam array(HMA) is compared in this paper.From calculation and result-analysis,it suggests that when compared to a 4-data-stream,128-element-subarray millimeter-wave(mmWave) HMA,the system energy efficiency of the AFDMA is better than that of the HMA when its transmit beams are greater than 63(for a 128-element transmit array) or 77(for a 256-element transmit array).This conclusion is the same as that when the receive beams of the AFDMA are greater than 17(for a 128-element receive array) or 23(for a 128-element receive array).更多还原
