There has been a tremendous growth in the joint source channel coding techniques of recent wireless communication system. The main objective of this technique is to simplify the architecture which eliminates the network errors and instability. This chapter mainly focuses on Joint Source Channel Coding (JSCC) in Multiple Input Multiple Output (MIMO) diversity to minimize the effects of noise, distortion and related phenomena for better reception of the signal with increased efficiency and spectrum utilization with link reliability. JSCC techniques in presence of 3G/4G/LTE-A for high data rate communication with the carrier aggregation is an important element for communication over wireless channel. In this chapter, the authors shall discuss the current state of research, the challenges related to the deployment of JSCC, the likely solutions and the usefulness as part of upcoming communication networks. A major part of the work shall focus on their suitability in LTE-A frameworks so essential for sustaining the current growth in wireless communication.

In this paper, we describe the design and implementation of a rake receiver for use with ultra wide band (UWB) systems. The rake receiver uses spread spectrum modulation (SSM) aided by kasami sequence generator. The combination is found to be effective in dealing with multipath fading and signal to noise ratio. The design is initially simulated using MATLAB 7.10 and is implemented using a HDL coder. The design is also implemented in a FPGA kit and is found to be effective in interference mitigation as part of a CDMA framework.
