Wideband multicarrier receivers are an interesting technology for software-defined radios. When combined with suitable digital signal processing hardware and software, they enable flexible adjustment of the number of carriers as well as provide the c

We analyze a new interference suppression structure in direct-sequence spread-spectrum (DSSS) systems that is based on two dimensional (frequency- and time-domain) notch filtering. In the first step, the filter is realized in the form of variable-ste

1997 IEEE International Conference on Personal Wireless Communications (Cat. No.97TH8338).
A method combining TDMA and CDMA in a digital cellular system is presented. This method makes use of complementary code sets. These codes have been selected due to their ideal autocorrelation and noninteracting characteristics. With these code sets o
