چکیده

A pre-coder is designed for orthogonal space-time block codes (OSTBCs) in multiple-input multiple-output (MIMO) channels. Unlike previous works, our pre-coder is the first to be designed to minimize the exact symbol error rate. In this paper, we show that OSTBCs can achieve full diversity and nearly strict orthogonality with a small amount of feedback bits returned from the receiver back to the transmitter. Along with pre-coding of the OSTBC, also the proper utilization of partial CSI is done at the transmitter side to improve overall characteristics of the system. Simulation results of the pre-coding OSTBC is discussed along with its antenna design technique.

Cooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Antenna Selection for MIMO Systems with Space - Time Coding

Multiple-Input multiple-output (MIMO) technology is capable of enhancing capacity and coverage of wireless links. Implementation of MIMO devices is intricate because of the increased number of radio frequency chains (one for each antenna element). Antenna selection is one attractive approach to mitigate this requirement. It only utilizes an optimal subset of all available antennas, adapting it ...

Achievable Unified Performance Analysis of Orthogonal Space-Time Block Codes with Antenna Selection over Correlated Rayleigh Fading Channels

In this paper we evaluated the performance of orthogonal space-time block codes with transmit antenna selection (TAS/OSTBCs) for frequency-flat correlated Rayleigh fading channels. By effective use of the probability density function (pdf), the bit error probability (BEP) for binary phase shift keying (BPSK) and M-ary Quadrature amplitude modulation (M-QAM) is derived first. Further we evaluate...
