The space time coding has evolved as a most vibrant research area in wireless communications recently, space-time block coding (stbc) has been trying to incorporate in the forthcoming generation of mobile communication standard which aims to deliver true multimedia capability. Block codes for the awgn channel, space-time block codes do not generally provide coding gain, unless concatenated with an outer code their main feature is the provision of full diversity with. In this final section, we present some performance results for orthogonal space-time block coding using four transmit antennas (4x1 system) using a half-rate code, g4, as per [ 4] we expect the system to offer a diversity order of 4 and will compare it with 1x4 and 2x2 systems, which have the same diversity order also.

Space-time coding is an important technique that promises greatly improved performance in wireless networks orthogonal space-time block coding for wireless communications provides detailed coverage of a technology that is already embedded in the umts and wcdma mobile standards.
It is shown that using multiple transmit antennas and space–time block coding provides remarkable performance at the expense of almost no extra processing index terms — diversity, multipath channels, multiple antennas, space–time codes, wireless communication. Wireless communications is, by any measure, the fastest growing segment of the communications industry as such, it has captured the attention of the media and the imagination of the public. Space–time block coding is a technique used in wireless communications to transmit multiple copies of a data stream across a number of antennas and to exploit the various received versions of the data to improve the reliability of data transfer.
Space-time block codes (stbc) is an efficient technique of sending data over a wireless channel a number of antennas are used at the transmitter in stbc multiple copies of the same data are sent over a number of different antennas according to the given codewords. An n xl (l_> n) space time block code (stbc) c over a complex signal set s con- sists of a finite number of n x i matrices with elements from $ for quasi-static, fiat fading channels a primary performance index of c is the minimum of the rank of the difference of any two codeword matrices, called the rank of the code.
