Abstract
Most of the physical layer designs are verified through the derivation and simu-
lation. However, there are several factors that mathematical model cannot take
into considerations. The theoretical analysis is not enough to describe the real-
world situation. Researchers used to implement the physical designs by Digital
Signal Processor (DSP) or Field Programmable Gate Array (FPGA). Though, the
hardware programming makes the testbed difficult to implement. The Software De-
fined Radio (SDR) becomes prevalent for its convenience and reconfigurability. In
this thesis, we design the wireless communication system utilizing the platform of
GNU Radio and Universal Software Radio Peripheral (USRP). First, we construct
a Bit-Interleaved Coded Modulation (BICM) system. The performance in terms of
packet error rate is also evaluated in our implementation. Next, we extend the SISO
OFDM into MIMO OFDM system. The designs of MIMO OFDM synchronization
and channel estimation are conducted in this system. Furthermore, a cooperative
communication system is verified in the real world transmission as well. A modified
Physical Network Coding (PNC) scenario is designed and demonstrated its feasibil-
ity. Finally, we list the advantages and difficulties when implementing these systems
using GNU Radio and USRP.
