摘要： The present invention provides a system (300-400), apparatus (300-400), and method for an energy-based antenna selection technique in which the antenna that observes the largest SNR averaged over all carriers per sub-band (405) is selected for space-time coded MB-OFDM systems. Due to the frequency-selective nature of the system, different sub-band may have different channel gaining effect from the multi-path channels. We can perform energy-based antenna selection per sub-band, and the simulation results show that the proposed technique works not only for MB-OFDM UWB channels with shadowing, but also for the same channel without shadowing.
摘要翻译：本发明提供一种用于基于能量的天线选择技术的系统（300-400），装置（300-400）及其方法，其中观察每个子带（405）在所有载波上平均的最大SNR的天线是选择用于空时编码的MB-OFDM系统。由于系统的频率选择性，不同的子带可能具有来自多路径信道的不同的信道增益效应。我们可以对每个子带进行基于能量的天线选择，仿真结果表明，该技术不仅可以用于具有阴影的MB-OFDM UWB信道，而且对于没有阴影的相同信道也是有效的。

摘要： A data transmitter transmits data packets comprising a plurality of symbols. The data transmitter maps symbols in at least one of the data packets using a single-carrier transmission format, and maps symbols in at least another of the data packets using a multi-carrier transmission format. The data transmitter maps the symbols using the multi-carrier transmission format when the characteristics of a communication channel over which the data packets are transmitted satisfy a first set of conditions, and maps the symbols using the single-carrier transmission format when the data transmitter determines that the characteristics of the communication channel do not satisfy the first set of conditions. A receiver processes the data packets according to which transmission format was employed in transmission.

摘要： A Single Carrier Block Transmission (SCBT) system employs an inherently parallel approach to error correction processing. At the transmission system (200), an incoming data stream is split (210) into P parallel data streams, each having a data rate equal to a fraction of the incoming data stream's data rate. The parallel data streams are then each separately encoded (220) in P parallel encoding processes (beneficially, using P parallel encoders (222)). The P separately encoded data streams are then merged (330), interleaved (320), and mapped (310) into a single stream of encoded symbols, which are transmitted to the receiver using an arbitrary modulation (240) and transmission scheme. At the receiver (255), the received data stream is de-interleaved (350) and split into P encoded data streams, which are then decoded (285) using P parallel decoders. Then, the decoded data streams are combined or multiplexed (295) into a single data stream.

摘要： The system, apparatus and method of the present invention provides a single carrier block transmission with guard interval as a means of communications over multi -path channels that enables frequency domain equalization, and therefore, has many of the advantages of OFDM, but does not have some of the drawbacks such as high PAPR and the need for high resolution ADCs. While the use of guard intervals in single carrier communications enables low complexity detection of the signal, it reduces bandwidth efficiency. The present invention improves the bandwidth efficiency by adjusting the length of the guard interval adaptively. Also, by allowing both time -domain and frequency domain equalizations, besides improving bandwidth efficiency, the inventions allows for great flexibility in receiver design.
