Two design parameters, SNR and correlation, are key factors for enhancing channel capacity in MIMO systems. Achieving high SNR and low correlation is desirable in antenna design. This paper discusses the relation between channel capacity and these two parameters, and presents simple formulas of this relation for propagation channels and antenna coupling of mobile terminals. According to these g...

A body area network (BAN) is a network of bodyworn or implanted electronic devices, including wireless sensors which can monitor body parameters or to detect movements. One of the big challenges in BANs is the propagation channel modeling. Channel models can be used to understand wave propagation in and around the human body and they are essential for antenna design, protocol design and the des...

A brief overview of MIMO-OFDM system design has been discussed and its key techniques are introduced. It also focuses on OFDM-based air interface, spatial channel modelling, transceiver design, channel estimation and minimizing the BER ratio by modifying the Maximum Likelihood function through channel estimation.

By only sending the parity bits, joint source-channel coding can be natively achieved with lowdensity parity-check codes. However, the code ensemble design of optimal low-density parity-check codes for joint source-channel coding over asymmetric communication channels is difficult. To circumvent such a difficulty, source-channel adaptors is proposed in this paper. By using the source-channel ad...

In modern communication technology design of inverse filter i.e. channel equalizer on receiver side is important in order to combat the effects of channel distortion. In this paper we address different approaches of inverse filter design. The different approaches used are based on second order statistics methods such as Shank’s algorithm, WienerHopf equations (both FIR and IIR), LMS algorithm. ...

In this paper, the main aim is to design and simulate UTRA FDD control channel in the presence of noise and wireless channel by using FDD library/Matlab box set that can be used to design and implement some systems. Moreover, a test and verification of the library is achieved with different channel models such as Additive White Gaussian Noise (AWGN), fading and moving channel models. FDD librar...

We propose three new design algorithms for jointly optimizing source and channel codes. Our optimality criterion is to minimize the average end-to-end distortion. For a given channel SNR and transmission rate, our joint source and channel code designs achieve an optimal allocation of bits between the source and channel coders. Our three techniques include a sourceoptimized channel code, a chann...
