摘要：

In this paper different SORN (Sets Of Real Numbers) datatype configurations are analyzed for unum type-2-based arithmetic applied to symbol detection in a wireless MIMO communication system. Different SORN interval properties and MIMO-specific performance measures as well as the corresponding hardware architectures are evaluated in order to rate the suitability of the different configurations for the target application. The evaluation of the proposed datatypes indicates an improvement in the solution set reduction of up to 95.4% and a hardware complexity reduction of 30.3% comparing the proposed 17 bit configuration to the original unum type-2-based 16 bit SORNs.
