Simplified multiple input multiple output (MIMO) communication schemes for interchip and intrachip communications

摘要

Aspects disclosed in the detailed description include simplified multiple input multiple output (MIMO) communication schemes for interchip and intrachip communications. In exemplary aspects, MIMO techniques are applied to interchip and intrachip communication systems. In particular, a programmable control function is provided at an electrical signal source and supports a default MIMO communication scheme on a MIMO channel comprising possible communication paths among a plurality of transmitting and receiving endpoints. In addition, the programmable control function can opportunistically employ a simplified MIMO communication scheme when the MIMO channel is determined to be a tri-diagonal MIMO channel. The simplified MIMO communication scheme uses an Inverse Fast Fourier Transformation (IFFT) with reduced computational complexity. By employing the simplified MIMO communication scheme, interchip or intrachip communication may be supported with reduced implementation complexity, lower power consumption, and improved robustness.
