Resource Efficient Implementation of Low Power MB-OFDM PHY Baseband Modem With Highly Parallel Architecture

Timing and carrier synchronization in wireless communication systems: a survey and classification of research in the last 5 years

“…3) Literature Review: The summary of the research carried out to achieve timing and carrier synchronization in UWB communication systems is given in Table XIX: 1) Timing synchronization alone considering IR-UWB communication system is studied in [386,388]. 2) Carrier synchronization alone is studied in [383,385,387,389,390,391,392,393,394], where as identified in second column of [384] and [395,396], respectively. As detailed in Table XIX, the categorized papers differ in respects of providing joint channel estimation, requiring CSI or training, proposing estimation or compensation, or providing lower bounds.…”

Efficient Integer Frequency Offset Estimation Architecture for Enhanced OFDM Synchronization

“…Field programmable gate arrays (FPGAs) have been used to implement software radio systems for over two decades, and provide an ideal platform which is higher performance, and lower power compared to processor-based software radio [10]. Several authors have presented hardware implementations of OFDM-based systems in the literature [11], [12], [13], [14], but these implementations do not include IFO estimation (only FFO). Without IFO correction, worst-case CFO must not exceed the largest supported FFO.…”
