可用于提高未来移动的设备在6 GHz以下频率的吞吐量的带宽可以通过聚合多个非连续频带来增加，所述多个非连续频带可以使用相同或不同的无线电接入技术来发送信息。然而，利用传统的无线电技术，每个频带需要完整的射频（RF）链，由于移动的站（MS）中的空间和能量消耗约束而限制了可能的增加。本文提出并测量了一个单一的RF链无线电同时接收三个非连续的频带传输16-QAM LTE信号，使用可调模拟前端和软件定义无线电（SDR）技术。在最坏情况下的并发接收的接收机的灵敏度仅下降了6dB相比，一个单一的频带的接收。这表明，复杂的信令技术可以与单个无线电链同时接收，同时满足3GPP标准，为未来标准的紧凑，高效，多频带接收器开辟了道路。
The bandwidth available for improving throughputs to future mobile devices at sub-6 GHz frequencies can be increased through aggregating multiple non-contiguous bands, which may be using the same or different radio access technologies to transmit information. However, with conventional radio technology, a complete radio frequency (RF) chain is required for each band, limiting the possible increase due to space and energy consumption restraints in the mobile station (MS). This paper presents and measures a single RF chain radio for concurrent reception of three non-contiguous bands transmitting 16-QAM LTE signals, using a tunable analogue front-end and software defined radio (SDR) techniques. The receiver sensitivity is degraded by only 6dB under worst-case concurrent reception, compared with reception of a single band. This demonstrates that complex signaling techniques can be received concurrently with a single radio chain while meeting the 3GPP standards, opening the way to compact, efficient, multiband receivers for future standards.
