We propose a code rate-diversity tradeoff scheme for wireless communications in which we combine cooperation with existing G2 orthogonal space-time block codes (OSTBCs) utilizing linear block codes for MIMO slow Rayleigh fading channels. Achieving the substantial diversity gains of the MIMO channel requires both linear block codes and OSTBCs that can take advantage of these channel resources. Simulation...
In this study, we present the suitability of UWB for WSN by simulating a DS-UWB digital transmission system using Matlab. DS-UWB is a single-band approach that uses narrow UWB pulses and time-domain signal processing combined with direct sequence spread spectrum (DSSS) techniques to transmit and receive information. Due to signal spreading, transmitted power becomes very low which paves to low probability...
