  The most common cause of transmission failure in Wireless High Performance
(WirelessHP) target industry environments is impulse interference. As
interleavers are commonly used to improve the reliability on the Orthogonal
Frequency Division Multiplexing (OFDM) symbol level for long packet
transmission, this paper considers the feasibility of applying short-packet bit
interleaving to enhance the impulse/burst interference resisting capability on
both OFDM symbol and frame level. Using the Universal Software Radio
Peripherals (USRP) and PC hardware platform, the Packet Error Rate (PER)
performance of interleaved coded short-packet transmission with Convolutional
Codes (CC), Reed-Solomon codes (RS) and RS+CC concatenated codes are tested and
analyzed. Applying the IEEE 1613 standard for impulse interference generation,
extensive PER tests of CC(1=2) and RS(31; 21)+CC(1=2) concatenated codes are
performed. With practical experiments, we prove the effectiveness of bit in
terleaved coded short-packet transmission in real factory environments. We also
investigate how PER performance depends on the interleavers, codes and impulse
interference power and frequency.
