Suboptimal Greedy Power Allocation Schemes for Discrete Bit Loading
We consider low cost discrete bit loading based on greedy power allocation (GPA) under the constraints of total transmit power budget, target BER, and maximum permissible QAM modulation order. Compared to the standard GPA, which is optimal in terms of maximising the data throughput, three suboptimal schemes are proposed, which perform GPA on subsets of subchannels only. These subsets are create...
متن کاملA Rate Adaptive Bit-loading Algorithm for a Discrete Multi-tone Modulation System in Downstream Power Line Communications
This paper deals with a variable rate Discrete Multitone Modulation (DMT) communication system for broadband Power-Line Communications (PLCs), based on the bit-loading algorithm proposed by Leke and Cioffi. In the proposed system a proper LMS channel estimator will be considered, which is based on the insertion of a Training Sequence (TS). The proposed approach will be compared with ideal chann...
متن کاملBit-loading Algorithm for DMT Broadband Indoor Power Line Communications
In this paper, a bit-loading algorithm for DMT (Discrete MultiTone) broadband indoor power line communications is proposed. In noisy channels with high attenuation values, most of the carriers remain empty after the application of conventional strategies. This is due to the limitation in the power spectral density (PSD) mask for the transmitted signal imposed by regulations. Under these circums...
متن کاملA New Loading Algorithm for Discrete Multitone Transmission
| A new loading algorithm for discrete multitone transmission is proposed. Thereby rate is not distributed according to channel capacity, but rate and transmit power are assigned to maximize the signal{to{noise ratio in each carrier. Because closed form expressions can be derived the algorithm is of very low complexity, even lower than the loading algorithm recently proposed by Chow et al. [3]....
متن کاملDSP implementation of a bit loading algorithm for adaptive wireless multicarrier transceivers
In this paper, we present a proof-of-concept, fixed-point, DSP hardware implementation of an adaptive bit loading algorithm that is designed for wireless multicarrier transceivers. Adaptive bit loading is used to enhance the performance of multicarrier transceivers by tailoring the subcarrier signal constellations to the channel conditions, which can vary across the subcarriers. Since most bit ...
