MIMO OFDM | Documentation? | Performance Benchmarks

This page presents some physical layer benchmarks for the WARP MIMO OFDM Transceiver. For higher-layer benchmarks (like throughput), please refer to one of the OFDM Reference Design applications.

Methodology

The tests below were conducted using the OFDM PHY included with OFDM Reference Design v14. The test setup consisted of two WARP kits (SISO Kit v1) whose radio boards were connected via coax cables and 80dB series attenuation. A laptop was used to generate traffic, consisting of 1454 byte Ethernet frames consisting of random data which changed with each packet. The nodes were configured to transmit these packets in one direction, with both nodes tracking statistics (Tx packet count, Rx good/bad packet count and BER).

Results

Packet Error Rate: PER is measured by transmitting a known number of packets, then counting how many are received successfully. A packet error occurs either when the receiver fails to detect a packet or receives it with at least one bit error in the header or payload.
