OFDM Code-Division Multiplexing with Pre-Equalization for Mobile Communications
نویسنده
چکیده
In this paper, the potential of orthogonal frequencydivision multiplexing-code-division multiplexing (OFDM-CDM) combined with the pre-equalization is investigated. The codedivision multiplexing (CDM) component within an orthogonal frequency-division multiplexing (OFDM) system enables additional diversity in frequencyand time-selective mobile radio channels. While, by applying pre-equalization at the OFDMCDM transmitter the task of equalization at the receiver can be completely avoided. Different pre-equalization techniques are investigated, and it is shown that pre-equalized OFDM-CDM systems can achieve promising performance in fading channels.

We present a combined orthogonal frequencydivision multiplexing (OFDM) and code-division multiple-access cellular system. It is derived from the OFDM model by introducing an extra code-shift division multiple access layer. This mitigates intercell interference without affecting intracell orthogonality and such property can be maintained in multipath environments. The new scheme is suitable for ...
