Abstract—All kinds of wireless communication systems face the difficulties of multipath, signal fading, increasing interference and limited spectrum. A productive approach to secure against deep fades is to utilize the differing diversity techniques. The primary idea behind all diversity techniques is to provide multiple uncorrelated replicas of the same information bearing signal over multiple independently faded paths. There are different types of diversity schemes that are applied upon the characteristics of the channel and additionally the transceiver structures. Some common diversity techniques that have been applied in practice include time diversity (e.g., channel coding, interleaving), spatial diversity (e.g., Multiple-Input Multiple-Output (MIMO) systems), and combination of multi-path and frequency diversity (e.g., Orthogonal Frequency Division Multiplexing (OFDM) systems. To exploit the benefits of MIMO and OFDM systems, precoding and/or joint precoding and decoding design for MIMO and OFDM systems is of great meaning and has been widely studied. The major aims of this survey paper is to show the advantage of applying the various precoding and/or decoding method to enhance the performance of the system as far as both the Bit Error Rate (BER) and capacity. Also, it considers the various assumptions about the Channel State Information (CSI) as the performance of MIMO and OFDM systems depending on the availability of the either perfect or imperfect CSI and channel correlation information.
