Power aware implementation of wideband code division multiple access (WCDMA) based system for mobile consumer devices in ad hoc settings

摘要

This paper presents the use of WCDMA techniques in mobile consumer devices based communication system used in ad hoc settings. The paper presents power aware techniques by listing area/power tradeoffs while deciding different word lengths of the datapath. The WCDMA is used in an ad hoc setting that requires mitigation of multi path fading effects in the communication system. A hybrid approach for effective equalization and cancellation at the receiver is presented. The implementation of the technique is then optimized for low power operation. The use of QAM modulation is also incorporated for high data rate operation in higher SNR environment.
