An efficient bit allocation algorithm for multicarrier modulation [PDF]
2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004 We present an efficient bit allocation algorithm for multicarrier systems operating in frequency-selective environment. The proposed algorithm strives to maximize the overall throughput while guaranteeing that the mean bit error rate (BER) remains below a prescribed threshold.

Modified SNR Gap Approximation for Resource Allocation in LDPC-Coded Multicarrier Systems
IEEE Access, 2020 The signal-to-noise ratio (SNR) gap approximation provides a closed-form expression for the SNR required for a coded modulation system to achieve a given target error performance for a given constellation size. This approximation has been widely used for

Duplexing methods for PON systems using multimode fiber with multicarrier transmission [PDF]
, 2005 Deploying a PON using multimode fiber in the access network is viewed as a costeffective solution. However, a multimode fiber link exhibits a time-dispersive nature. To cope with this problem, an OFDM transmission method is used.

Joint Decoupling Optimization of Frequency Offsets and Array Elements for Frequency Diverse Arrays
International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.Frequency diverse array (FDA) has a distance‐angle–dependent beam direction map, which has a greater application advantage than phased array. However, due to the distance‐angle coupling and periodicity of its beam direction map, it makes the parameter information of the target obtained through FDA have ambiguous phenomena. Currently, researchers mostly

Pulse Shaping, Localization and the Approximate Eigenstructure of LTV Channels
, 2008 In this article we show the relation between the theory of pulse shaping for WSSUS channels and the notion of approximate eigenstructure for time-varying channels. We consider pulse shaping for a general signaling scheme, called Weyl-Heisenberg signaling,
