该论文提出了一种支持LTE Rel-11及后续版本非连续载波聚合的接收机架构，解决了在手机中实现非连续载波聚合时面临的总带宽跨度大、干扰复杂等挑战。
Jim Svensson, Fenghao Mu, Thomas Olsson, Imad ud Din, Leif Wilhelmsson, Daniel Eckerbert, Sven Mattisson Ericsson, Lund, Sweden Carrier aggregation (CA) is introduced in 3GPP LTE Rel-10 [1] to meet the demand for further increased bitrates. While LTE Rel-10 supports simultaneous reception of two carriers either in contiguous intra-band or in inter-band CA configuration, the upcoming LTE Rel-11 will add support for non-contiguous (NC) carriers within bands. Supporting NC CA in handsets is a demanding challenge for several reasons. Foremost, the total bandwidth spanned by the carriers may be several times the bandwidth of the individual carriers, possibly spanning an entire band with interfering signals between desired carriers. Furthermore, the distance between TX and RX carriers will vary and worse, may be much smaller than the fixed duplex distance for LTE Rel-8 and W-CDMA single carrier operation [2-5].
