A sub-band based ultra wideband (SUWB) system is proposed. The technique provides scope for using the ultra wideband bandwidth efficiently by exploiting the available link margin for short range communications. The bandwidth of 500 MHz or more is divided into a fixed number of subbands. The data transmission scheme over multiple sub-bands can be designed to(More)
In sub-band ultra-wideband (SUWB) systems, the use of spreading codes in conjunction with sub-banding enables energy efficient reduced sampling rate receiver designs. In this work, the orthogonal frequency division multiplexing (OFDM) technique is proposed for SUWB systems as a means to mitigate the multipath fading effects of the channel. The OFDM(More)
