PERFORMING FREQUENCY DOMAIN PROCESSING IN TD-SCDMA SYSTEMS

摘要

In a TD-SCDMA system, there are at least two pilot signals, namely the midamble and the downlink pilot time slot (DwPTS). The midamble sequence has a cyclic prefix. As a repetition of the end of the midamble sequence, the cyclic prefix allows for frequency domain processing of the midamble sequence, such as channel estimation. The DwPTS sequence, however, does not have a cyclic prefix and, therefore, may not be amenable to the frequency domain implementation. Therefore, certain aspects of the present disclosure provide techniques for implementing frequency domain processing for both the midamble and DwPTS sequences, in an effort to reduce implementation and testing options.
