It is achieved by equally weighting the memory terms in conventional DPD models that leads to a significant reduction of numerical calculation complexity in the coefficients updating process and thus saves time and power during real system operation. To validate the proposed method, both wideband LTE- A (100 MHz) and concurrent dual-band (20 MHz + 20 MHz) cases have been tested. Experimental results show that the proposed method can achieve excellent performance with significant reduction of system complexity compared to the conventional approaches.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2015 IEEE||Keywords:||Digital predistortion; Dual-band; Model extraction; On-line updating; Power amplifier; Wideband||DOI:||10.1109/apmc.2015.7411574||Language:||en||Status of Item:||Not peer reviewed||Is part of:||2015 Asia-Pacific Microwave Conference (APMC2015) Proceedings||Conference Details:||The 2015 Asia-Pacific Microwave Conference (APMC2015), Nanjing, China, 6-9 December 2015||ISBN:||9781479987658|
