In Multiple Input Multiple Output (MIMO) systems, predicting performance prior to data transmission is needed to appropriately select transmitter parameters (e.g. power, code rate). The prediction must be both accurate and easy to compute, given limited resources. An algorithm taking too much time to run or excessive circuitry to implement cannot be deployed. This paper presents an algorithm to predict...
In multiple input multiple output (MIMO) systems, predicting performance prior to data transmission remains a difficult problem. This paper proposes an algorithm to predict the average bit error rate (BER) and packet error rate (PER) of a MIMO system, after decoding the error correction code (ECC). Since the algorithm makes no a-priori assumptions about the channel, it is applicable to a wide variety...
In multiple-input multiple-output (MIMO) systems, accurately predicting performance prior to data transmission remains a difficult problem. This paper proposes an algorithm to predict the bit error rate (BER) and packet error rate (PER) of a MIMO system with turbo coding. First, we modify the union bound (UB) with the help of Craig's formula to make it more amenable to random channels. Second, we...
This paper presents results from a MIMO measurement campaign designed to demonstrate spectral efficiencies of 13.7-26.0 information bits per second per Hz (bps/Hz) using an 8times8 test bed over a range of outdoor wireless channels with low antenna heights at each end of the link. Links included line-of-sight and non-line-of-sight channels obstructed by foliage and buildings. Measurements were performed...
