In this paper we study the performance of two downlink multi-cellular systems: a Multiple Inputs Single Output (MISO) system using the Alamouti code and a Multiple Inputs Multiple Outputs (MIMO) system using the Alamouti code at the transmitter side and a Maximum Ratio Combining (MRC) as a receiver, in terms of outage probability. The channel model includes path-loss, shadowing and fast fading ...

Space-time codes were designed for fading environments in order to improve system capacity and/or to achieve a diversity gain. In this paper, a novel possible application of the Alamouti space-time block code (STBC) for two transmit antennas is investigated, to provide a switchless alternative in current resilient microwave radio links. Resilient means that transmitter (Tx) and receiver (Rx) ar...

The golden code is a full-rate full-diversity space-time code for the two-input two-output channel with good performance but high decoding complexity. The overlaid Alamouti codes were recently proposed as an alternative; in exchange for a slight performance penalty, they have lower decoding complexity on quasistatic channels with QAM alphabets. However, the complexity advantage of the overlaid ...

A full diversity block space-time code over two transmit antennas and two symbol periods is introduced. The proposed method results in substantial performance improvement over the widely used scheme of Alamouti [1] and at the same time allows for a simple maximum likelihood decoding algorithm.

In this paper, the neax-far resistance of the MMSE detector is derived for the code division multiple access (CDMA) communication systems with the Alamouti space-time block coding. It is shown that transmitter/receiver diversity has benefits on the near-far resistance performance while receiver diversity has more impact on theTTear-far resistance.

In most commercial wideband code division multiple access systems, the transmitted signal in the downlink channel is spread by orthogonal codes to accommodate different users. However, frequency selective fading destroys the orthogonality and causes multiple access interference. Application of a chip level decision feedback equaliser with the Alamouti transmit diversity scheme is proposed to re...

Over the last couple of years a number of spacetime block codes have been proposed for use in multiple transmit antennas systems. In this article we propose a method to extend any space-time code constructed for m transmit antennas to m p transmit antennas through GroupCoherent Codes (GCC). GCC make use of very limited feedback from the receiver (as low as one bit). In particular the scheme can...

Transmit diversity schemes for filter bank multicarrier (FBMC) are known to be challenging. No existing have considered the presence of inter-antenna frequency offset (IAFO), which will result in performance degradation. In this letter, a new transmit scheme based on reversal Alamouti code (FRAC)-based structure address issue IAFO is proposed and proven inherently cancel inter-carrier interfere...

Multiple-input and multiple-output, or MIMO, is the use of multiple antennas at both the transmitter and receiver to improve communication performance. MIMO technology has attracted attention in wireless communications, because it offers significant increases in data throughput and link range without additional bandwidth or transmit power. In this paper, multiple-input–multiple-output (MIMO) sy...
