Conclusion

In this chapter, we reviewed the basic concepts, models, and approaches for BSS and BE. Furthermore, the connection between the BSS and BE was also discussed. In Chapters 3

and 4, we will explain how the ICA-based algorithms, which have been used in BSS problems, can be applied to obtain BE under certain constraints. In Chapter 5, the idea of relative gradient will be used to improve the standard Bussgang-type BE algorithms for better performance. In Chapter 6, channel shortening for OFDM systems with the relative gradient will be shown.
