In this paper, we present two space-time schemes for exploiting diversity in multi-antenna impulse radio ultra wide-band (IR-UWB) systems when neither the transmitter nor the receiver has access to channel state information. ...

In this paper, we propose a new space time (ST) coding scheme for time hopping (TH) ultra wideband (UWB) systems. The proposed scheme encodes the pulses used to transmit one information symbol. This permits to achieve full ...

One of the major challenges for optical network operators is related to realizing profitable networks that preserve the overall satisfaction of their end customers. This necessitates ensuring a controlled network resource ...
