We investigate the effects of microwave ovens interference on the performance of digital radio communications systems (PDC, PHS, ISM-band (2.45 GHz) wireless LAN). At first, we experimentally measure the interference radiated from microwave ovens and discuss the statistical characteristics of interference. Then, by using the measurements results, the effects of interference on the performance of π/4-shift QDPSK and DS/CDMA systems are evaluated. Numerical results conclude that the performance of digital radio communication systems are significantly degraded by the effect of interference. Moreover, we propose a new TDMA channel assignment method for microwave oven interference and investigate the performance improvement achieved by proposed channel assignment
