Optimum combining in digital mobile radio with cochannel interference

Abstract: -This paper studies optimum signal combining for space diversity reception in cellular mobile radio systems. With optimum combining, the signals received by the antennas are weighted and combined to maximize the output signal-to-interference-plus-noise ratio. Thus, with cochanne1 interference, space diversity is used not only to combat Rayleigh fading of the desired signal (as with maximal ratio combining) but also to reduce the power of interfering signals at the receiver. We use analytical and computer simul… Show more

“…To cope with interference, smart antennas or adaptive array processing can be utilized to shape the antenna radiation pattern in such a way as to enhance the desired signals and null the effect of the interfering signals [1][2]. In Some results are provided in Figure 5 for BPSK where there is one interferer with an SIR of 10dB.…”

“…These technologies must be able to cope with the challenging wireless environment and antenna systems in the form of adaptive arrays or smart antennas can provide an effective and promising solution while achieving reliable and robust high speed and high data rate transmission. Such systems have been proposed for wireless communications for many years [1][2]. Recently, however, research and development in this area has significantly increased [3][4] and many commercial products are now readily available for wireless communication systems.…”

The 1 -dimensional symbols spanned by each of the components of the feedforward filter can be grouped as (9) We can define , which can be conveniently expressed as (10) where the extended sequence of symbols from the th transmitter is . .…”

“…In V-BLAST, every transmit antenna radiates an equal-rate independently encoded stream of data. This transmit structure enables the utilization, at the receiver, of interference rejection and cancellation techniques [9], [10] with the added advantage that the multiple streams are precisely synchronized. A V-BLAST receiver can be regarded, therefore, as a synchronous multiuser detector with ordered successive cancellation.…”
