In this thesis, we focus on the employment of mimo systems that use stbc to improve the ber performance of wireless communication systems in fading channels, as well as in channels based on actual field measurements. The stbc02 is a highly integrated power management, embedding a linear battery charger, a 150 ma ldo, 2 spdt load switches, a smart reset/watchdog block and a protection circuit module (pcm) to prevent the battery from being damaged under fault conditions. The alamouti code  is chosen as the target stbc to exploit that is an integer power of 2 called stbc-sm by considering the general stbc performance criteria proposed by tarokh et al respectively designed to take advantage of both sm and stbc 𝑢2. I abstract this thesis is concerned with channel estimation and data detection of mimo-ofdm communication systems using space-time block coding (stbc.
This thesis project i am deeply grateful to drjoakim jalden for providing invaluable advice and i am extremely impressed with his teaching, advising (stbc) system there are many other kinds of detection methods at the receiver that have been introduced for the space-time coding scheme, such as turbo decoding  and decision feedback de. The mimo alamouti code is a simple space time block code that he developed in 1998the alamouti code is a so called space-time block code (stbc) a block code is a code that operates on a “block” of data at a time and the output only depends on the current input bits. New approaches of implementing stbc technique and mimo-ofdm channel estimation prepared by: duaawaleed rawyaderiah walaahammoudeh bsc report.
In this paper, a novel semi-blind channel estimation and symbol detection based on space-alternating generalized expectation-maximization (sage) algorithm are proposed for space time block coded.

We will improve the ber performance of 64psk 4×2 stbc's systems (since it gives acceptable complexity and high bit rate) by com bining them with (8,4) exhamming turbo product code. The performance comparison between stbc and sfbc in ofdm system over slow fading channel (f d = 20 hz) is shown in figure 7, the performance of the two systems stbc and sfbc-ofdm in fast fading channel (f d = 100 hz) are shown in figure 8, and the performance of stbc and sfbc-ofdm in slow fading (f d = 20 hz) over frequency selective channel is.

Wireless communication analysis and practical issues this thesis is concerned with the use of multiple antenna elements in wireless communica-tion over frequency non-selective radio channels both measurement results and theoretical for beamforming and stbc is found in general are mimo fading channels correlated and. Imperfect channel estimation and synchronization by yi xiao a thesis (stbc)  to a practical system are the imperfect channel estimation and rough synchronization without the full knowledge of channel state information (c si), the receiver is highly likely to make.
411 analysis of the person’s usage by cooperative mimo with stbc plan the power consumed by various diversity orders (2‚2, 3‚3 and 4‚4) are presented for the stbc coded cooperative mimo plan using coalition game is proven fig3. Mimo-ofdm when generated ofdm signal is transmitted through a number of antennas in order to achieve diversity or to gain higher transmission rate then it is known as mimo- ofdm. The thesis have studied low-complexity channel estimation and detection techniques to improve the reliability of the wireless links or increase the spectral efﬁciency at low cost as follows.
Into a block fading channel, the stbc-tcm outperforms the sttc additionally, the performance is examined for different mapping techniques for the stbc-tcm system. In this thesis, a mimo-ofdm system that employs walsh sequences as block coding is designed simulation studies show that the proposed system exhibits high performance and comparisons show that it has low complexity compared to some of the previous systems.
