Software-defined radio implementation of multiple antenna systems using low-density parity-check codes

Rapid Prototyping for Evaluating Vehicular Communications

“…Only (27) and (34) make use of DSPs that have similar or superior characteristics. In terms of FPGA computational capacity, the testbed implemented is only worse than (28) but outperforms (19,20,30,33,34).…”

“…Other examples of this type of platforms can be found in (19,20,26,27,28,29,30,31,32,33,34). If the features of the implemented MIMO platform are compared with the others found in the testbeds cited, it can be concluded that:…”

“…However, at reception the testbed is limited to a carrier frequency of 2.4 GHz and a bandwidth of 20 MHz. Regarding this aspect, the platform implemented outperforms or equals the single-band platforms at 2.4 GHz (20,26,27,29,30,33,34) but is not capable of receiving signals at higher frequencies and/or higher bandwidths like (19,28,31,32).…”

A comparative study of STBC transmissions at 2.4 GHz over indoor channels using a 2 × 2 MIMO testbed

“…On the contrary, our MIMO platform fits into the second type, that is, testbeds designed according to a general purpose. Examples of this type of platforms can be found in [32][33][34][35][36][37][38][39][40][41][42]. To better explain the differences Copyright between platforms, we focus on the following features:…”

“…Our platform is very flexible at transmission because it utilizes commercial signal generators but not at reception where it is limited to a carrier frequency of 2.4 GHz and a bandwidth of 20 MHz. In this sense, our platform outperforms or equals the singleband platforms at 2.4 GHz [33][34][35]37,38,41,42] but is not capable of receiving signals at higher frequencies and/or higher bandwidths such as [32,36,39,40].…”
