Digitising the wireless MRI link: a space-time CDMA approach

In this paper an approach for digitising the wireless MRI unit to data processing unit link is presented. The proposed method is able to support multiple medical imaging devices functioning in a low signal to noise ratio environment. The architecture utilises the short code CDMA signalling format since this offers a number of advantages, and a novel joint-space time remote array receiver. The receiver output can be used to make reliable data symbol decisions even in conditions of low input Signal to Noise ratio. The theoretical framework is supported by computer simulation studies.
