International audienceThe industry has shown a growing interest in the field of in-house wireless communication. The two major technical challenges are the interference and the signal distortion by the communication channel. We propose three different interference mitigation and distortion compensation strategies. These strategies are based on frequency domain processing, which is best supported by orthogonal frequency division multiplexing (OFDM) and single-carrier modulation with cyclic prefix (SCCP). Both modulation techniques are compared with respect to their performance in an in-house environment. Both techniques are promising for in-house communication in an environment corrupted by interference and frequency selective channels

Recent developments show an increasing interest for wireless in-house multimedia communication within the 2.4 GHz ISM1-band. A disadvantage of the ISM-band is the high level of mainly narrowband interference, generated by other communication systems and by the leakage of microwave ovens. Good communication is therefore only possible when appropriate measures are taken to compensate for the interference. In this paper, we compare the performance of two different modulation techniques in the presence of narrowband interference. We consider OFDM and single-carrier modulation with frequency-domain processing. A static model of the Bluetooth[l] system is used as source of interference. Both modulation techniques are interesting for in-house communication due to the simpler frequency domain equalization.
