Talk Title:  Difficulties of the Implementation of MIMO-OFDM Chains as Software Defined Radio at Very High Speeds and Real-Time and the Needs for Using CBSE Connectors, Data Distribution Service and Multicore Platforms. 

Abstract:

The information theory shows that we could have very high transmission rates, depending on the number of transmit and receive antennas. However, the radio channel imposes, unfortunately, some significant limitations, in consideration to  its coherence bandwidth and coherence time. The MIMO-OFDM techniques are currently the best ones to ensure trade with very high speeds. The application of these techniques, in addition to traditional wireless communications include medical imaging, 3D Radar imaging and 3D thru-wall applications.

A MIMO-OFDM chain can be seen as a succession of high dimensional matrix multiplications. The estimation of the channel response, in order to achieve signal detection, requires optimization techniques and it is the same for the synchronization function, which demand enormous computations. Unfortunately there are, in addition to these functions, performance degradations from different sources, as RF impairments,  which must also be removed within the reception chain.

It is no longer possible to compute, in real-time, 8x8, 16x16 or 32x32  MIMO-OFDM communications chains as conventionally by VHDL IP cores or by DSPs. The processing of MMO-OFDM chains by multicores, around NoC architectures, and using real-time middlewares, is obligatory.

We discuss in this intervention the usefulness of NoC structures to support multicores architectures. We also discuss the importance of the PUBLISH / SUBSCRIBE communication paradigm to support this architecture.  The 8x8, 16x16 or 32x32  MIMO-OFDM chains must use the decomposition of matrices to make matrix product or matrix inversions, for parallel processing purposes, dependent on the number of available cores. It is possible, in fact, that during the processing of the chain, several cores have published their downtime. The manger, responsible of matrices subdivision, must take account only of the available cores. Along a chain, the number of cores involved for the processing is no longer the same
