Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation’s cellular systems but has since then been improved and is reused in today’s 3G systems as Wideband CDMA. ISY is interested in getting a behavioural model of a W-CDMA system since they had developed a DSP processor called BBP1 and were thinking about adding W-CDMA support for it. Even though our system is not implemented on the BBP1 it should provide a good base for future implementations. This thesis project will describe the construction of a behavioural model of a W-CDMA system following the standard specified by 3GPP. The system simulates W-CDMA transmission and reception and has an optional channel used to simulate real world interference. The receiver uses a rake combiner to improve the performance of the system.

This thesis deals with a new multi-user technique: the Interleave Division Multiple Access (IDMA) proposed by Li Ping et al. , in 2002. This technique is a particular case of chip Interleaved Code Division Multiple Access (cI CDMA). The key principle of IDMA is that the chip interleavers are used for user separation. Moreover, the receiver is based on chip iterative detection, where a multiuser detector and decoders exchange extrinsic information in a turbo-like manner. IDMA systems are able to cancel the multi-user access interference and inter-symbol interference effectively, thanks to this iterative process and the user-specific interleavers. In this study, we first validate the performance presented initially by Li Ping et al. And then completed our study by a deep analysis of the IDMA principle. A major effort has been dedicated to the study of the trade-off between performance and complexity, since the complexity of the IDMA receiver in terms of number of operations increases with the number of users, the number of iterations and the number of paths. We have then proposed a new IDMA-based system in which receiver complexity is independent of the number of paths. This involves combining the IDMA technique with the multi-carriers modulation OFDM (Orthogonal Frequency Division Multiplexing). A comparison with the IDMA system based on the cancellation of inter-symbol interference has shown that the proposed OFDM-IDMA system improves the performance, in terms of binary error rate. Moreover, the receiver complexity, in terms of number of operations is greatly reduced. A study of the OFDM-IDMA system in the context of wireles communications allows us to consider this technique as a potential candidate for the air interface 4G. To do so, we have proposed a simplified detector for the IDMA receiver, whose performance in terms of binary error rate is closed to that of the original one. A comparison of performance and complexity with the original detector has shown that the proposed simplified detector is an interesting choice for the hardware implementation of an IDMA system. Finally, interleavers matched to hardware implementation have also been proposed as an alternative to the random interleavers of the theoretical IDMA system

Furthermore, studies on the information theoretical capacity of chip synchronous OCDMA channel with Single User Detection (SUD) is conducted to obtain the ultimate throughput that can be achieved. Calculations are done under three assumptions: (i) interference-limited channel, (ii) interference-limited channel with Gaussian noise; or (iii) Gaussian approximated interference channel. In additions, system specific DFSC and BCDD capacity is obtained. These results are used as the basis for comparison among DFSC, BCDD and other previously proposed OCDMA systems. It is found that the maximum throughput of an OCDMA system is limited to about 0.7 bits per OCDMA chip. With the application of turbo code, BCDD can support an aggregate throughput of about 0.42 bits per OCDMA chip.
