“…For a rather general class of channel models [12], this matrix is, in fact, the capacity-achieving precoder V when the receiver has perfect instantaneous channel-state information [channel-state information at the receiver (CSIR)], but the transmitter has only access to its distribution [channel distribution information at the transmitter (CDIT)]. This precoder is also shown to be optimal from an SINR standpoint with a linear MMSE receiver [2]. Fig.…”

“…To do so, a closed-form expression is needed, relating the average BER and the required transmission power for different candidate modulation schemes. Moreover, the transmitted signal may be optimized under other different criteria using a precoder [2]. A closed-form expression for the average BER is also useful, in general, for the system design, even if adaptive modulation or precoding is not used.…”

Abstract-This paper analyzes the average bit error rate (BER) of multiple-input-multiple-output (MIMO) systems in transmit-correlated Rayleigh flat-fading channels. The receiver scheme is based on the minimum mean square error (MMSE) criterion, and the input may be precoded to optimize the communication. Accurate closed-form formulations for the average BER are derived.Index Terms-Bit error rate (BER), correlated channel, Gamma distribution, minimum mean square error (MMSE), multipleinput-multiple-output (MIMO), signal-to-interference-plus-noise ratio (SINR).

Abstract-For single-user MIMO communication with uncoded and coded QAM signals, we propose bit and power loading schemes that rely only on channel distribution information at the transmitter. To that end, we develop the relationship between the average bit error probability at the output of a ZF linear receiver and the bit rates and powers allocated at the transmitter. This relationship, and the fact that a ZF receiver decouples the MIMO parallel channels, allow leveraging bit loading algorithms already existing in the literature. We solve dual bit rate maximization and power minimization problems and present performance results that illustrate the gains of the proposed scheme with respect to a non-optimized transmission.

“…Recently, two approaches have gained lot of attention, i.e. FilterBank based MultiCarrier (FBMC) modulation and Non-Orthogonal Frequency Division Multiplexing (NOFDM) [5][6][7][8][9][10][11][12][13]. In both schemes the consecutive user data symbols are transmitted on specific subcarriers, appropriately filtered in order to fulfill some predefined requirements.…”

Mercury-Waterfilling for Generalized Multicarrier Signaling

Orthogonal Frequency Division Multiplexing is often treated as the promising technique for next wireless or wired communication systems. Beside its great advantages, orthogonal frequency division multiplexing has also some weaknesses, such as high out-ofband emission or high peak-to-average power ratio, which become the basis for investigation on new transmission techniques. In this paper the application of the so-called generalized multicarrier (GMC) signaling is considered as a good solution for application in future systems, especially for cognitive-radio applications. It is characterized by high flexibility and adaptability of its parameters, thus allowing for e.g. low out-of-band emission. In this work the possibilities of application of link adaptation techniques have been analyzed, with the particular attention put on the mercury-waterfilling principle. Two approaches of application of this procedure in GMC systems have been proposed and analyzed by means of computer simulations.
