In this paper, the authors provide a survey among different types of channel estimation schemes for MC-CDMA. This paper reviews all possible channel estimation schemes for MC-CDMA and compares all schemes on the basis of performance and requirements. It is observed that each of the estimation technique has its own advantages and disadvantages. Some of the techniques have advantage of low complexity but on the other hand the performance degraded. Some techniques show better performance but complexities increases. Some of the estimation techniques have disadvantage of degraded performance for heavy load.
