Production and performance of thin and thick film NTCR thermistors based on NiMn(_2)O(_4)+δ [PDF]
, 2003 In this study reliable film type NTCR thermistors based on NiMn(_2)O(_4)+δ were produced and their electrical properties were studied in detail. Electron-beam evaporation procedures have been applied to produce thin film NTCR thermistors. Phase pure NiMn(

Successive Interference Cancellation in Clipped and Product Combining aided FFH Multi-User Systems
, 2006 —In this contribution, we propose two successive interference cancellation (SIC) schemes for a fast frequency hopping (FFH) multiple access (MA) system using M-ary frequency shift keying (MFSK) and invoking multi-user detection (MUD). One of the proposed
