In this paper, we consider user equipment which is not yet connected to a given UMTS-FDD network. We propose an algorithm which allows to the user equipment to estimate bit error rate (BER) of a potential downlink in term of the spreading factor and of the power that could be allocated by a base station to this virtual link. This problem is motivated by the context of cognitive radio. Our approach...
In this paper, a low complexity multicode MMSE chip-level channel equalizer for the downlink UMTS FDD mode is proposed. This equalizer has a Rake-like structure and does not need the knowledge of the spreading codes to compute the equalizer filter coefficients. Moreover, the equalizer depth is determined automatically using the knowledge of the channel impulse response and the noise variance. Thus,...
