Tiivistelmä

In this paper we investigate the time-frequency localization tradeoffs in practical implementation of filter bank multicarrier (FBMC) waveforms in short burst transmission. Frequency localization is considered as an important characteristic for future wireless communication systems, including 5G, but it comes with the cost of not-so-good time localization. This appears in the form of relatively long `tails' of the generated transmission burst. Truncation of the burst tails is an obvious choice for reducing the time-overheads in short burst based multiple access or duplexing schemes, but it introduces transients in the inband interference and out-of-band radiation characteristics. We study the burst truncation effects while utilizing a flexible FBMC waveform generation scheme based on fast-convolution processing. Also a novel method to optimize the used symbol waveform taking into account the truncation effects is developed.
