Wideband Digital Predistortion with SystemVue and PXI Modular Instruments

Application Notes

A transition is now underway in the wireless communications industry, as wireless service providers embrace broadband communication standards such as LTE-Advanced and IEEE 802.11ac. In order to achieve Gb/s link-level throughput, these new formats use wider bandwidths, multiple-input multiple-output (MIMO) space-time coding, and higher order orthogonal frequency division multiplexing (OFDM) modulation formats. These requirements place new demands on linearity, bandwidth and power consumption in wireless components. For example, LTEAdvanced supports up to 100-MHz bandwidth to reach 1Gb/s and 500 Mb/s data rates for the downlink and uplink, respectively. IEEE 802.11ac will support 80-MHz and 160-MHz bandwidths to achieve throughputs of at least 1 Gb/s for multi-station and 500 Mb/s maximum for a single link.
