Experimental implementation of cooperative transmission range extension in indoor environments

This paper presents an experimental comparison between cooperative communication and single-input single-output (SISO) system, in terms of the corresponding ranges of signal reception in each case. Transmissions have been achieved using Universal Software Radio Peripheral (USRP) platform, with the signal processing and time synchronization occurring in the GNU Radio environment. The method has been implemented in a typical office environment, with cooperative transmission (CT) taking place over a multiple hop network, using the binary phase shift keying (BPSK) scheme. Presented herein are comparisons between SISO and cooperative networks with regards to ranges and bit error rate (BER) performance.
