CA has already found its place in the deployment of 4G wireless networks. It successfully
shows its value as an efficient way to increase the signal bandwidth within the available …

Carrier aggregation is a key feature of 3GPP LTE that addresses the support of higher data
rates and utilization of fragmented spectrum holdings. In this article, the relevant design …

Contiguous/noncontiguous carrier aggregation (CA) is one of the key features from 4G
systems, which is expected to be evolved within 5G technologies. Thus, there is a need for …

To satisfy the ever increasing demand for higher throughput and data rates, wireless
communication systems need to operate in wider bandwidths. 3GPP LTE-Advanced with …

In order to achieve up to 1 Gb/s peak data rate in future IMT-Advanced mobile systems,
carrier aggregation technology is introduced by the 3GPP to support very-high-data-rate …

The initial release of LTE provided extensive support for deployment in spectrum allocations
of various characteristics, with bandwidth ranging roughly from 1.3 MHz up to 20 MHz in …

Multiple access and transmission enhancement in support of carrier aggregation techniques
has been actively studied in the 3GPP LTEAdvanced standardization process of the …

Long Term Evolution-Advanced (LTE-Advanced) provides considerably higher data rates

BACKGROUND Currently, the new cellular mobile communication stan dard LTE (long term
evolution) is being implemented glob ally. As one main new feature, this standard comprises …

We propose a complete receiver for separating cochannel signals in a time-division multiple-
access type system when the timing and carrier synchronization are imperfect or only …
