摘要： The problem of inefficient channel impulse-response processing is addressed by processing different parts of a channel impulse response to accurately locate channel taps, and to generate more than one set of equalization coefficients. This allows the most-suited equalization coefficient to be selected based on a selection criterion.

摘要： Channel estimation for high mobility OFDM channels is achieved by identifying a set of channel path delays from an OFDM symbol stream including carrier data, inter-channel interference noise and channel noise; determining the average channel impulse response for the identified set of channel path delays in each symbol; storing the average channel impulse responses for the identified channel path delays; generating a path delay curvature for each channel path delay in each symbol based on stored average channel impulse responses for the identified channel path delays; estimating the carrier data in the symbols in the OFDM symbol stream in the presence of inter-channel interference noise and channel noise from the OFDM symbol steam and the average impulse responses for the identified channel path delays; reconstructing the inter-channel interference noise in response to the path delay curvature, the identified set of channel path delays and estimated carrier data; and subtracting the reconstructed inter-channel interference noise from the OFDM symbol stream to produce a symbol stream of carrier data and channel noise with suppressed inter-channel interference noise.

摘要： In the technology known today, UWB transceiver power consumption is not efficient and too high. We have solved this problem. In our patent we have presented our innovationist UWB transceiver circuit, which could be used for preamble based OFDM or pilot based OFDM reception. In IEEE P802.15-03/268r3 it is reported that UWB OFDM receiver power consumption at 480Mbits/sec, when implemented using traditional digital method, is 323mwatts for 130nm, and 236mwatts for 90nm. We have found that implementation of the same receiver using our new innovationist OFDM receiver, working at 480Mhz, consumes about 40mwatts. It is clear, in terms of power consumptions, that our OFDM receiver implementation is 8 times lower than the lowest power consumption known today by OFDM receiver circuit.

摘要： The theme of our patent is an ultra low power components for Orthogonal Frequency Division Multiplexing (OFDM) based receiver. A new and innovationist OFDM receiver components ("our OFDM receiver components"), based on discrete time analog signal processing, are described in this patent application. OFDM receiver circuit is usually related to a communication field, where it is used to receive and decode a transmitted data. OFDM receiver circuit gets at its input OFDM modulated signals, and performs all necessary tasks, in order to decode the received data. OFDM signal comprised of multiple orthogonal carrier (103a- 105a), in which each one carries different data symbol. The summation of all carrier symbols comprises the data. To perform the receiving operation, an OFDM receiver must first perform detection, synchronization, parameter and channel estimation, then, a Fast Fourier Transform (FFT) is applied, and then, equalization is performed, and the last stage, is the de-interleaving and the error correction. All tasks above require complicated computational operations, such as additions, multiplications. Therefore, if implemented in a digital way, as it is with the current known technology, a significant high power is consumed by the receiver. Our OFDM receiver components are built and designed to work with discrete time analog signals, based on extremely low power additions, multiplications operations, and therefore achieves significant power reduction, compared to its digital counter implementation.
摘要翻译：我们的专利主题是基于正交频分复用（OFDM）接收机的超低功耗组件。在本专利申请中描述了基于离散时间模拟信号处理的新的和创新的OFDM接收器组件（“我们的OFDM接收器组件”）。 OFDM接收机电路通常与通信领域相关，其中它用于接收和解码发送的数据。 OFDM接收机电路获取其输入的OFDM调制信号，并执行所有必要的任务，以解码接收到的数据。 OFDM信号由多个正交载波（103a-105a）组成，其中每个载波携带不同的数据符号。所有载波符号的总和包括数据。为了执行接收操作，OFDM接收机必须首先执行检测，同步，参数和信道估计，然后应用快速傅里叶变换（FFT），然后进行均衡，最后一个阶段是解交织和纠错。上述所有任务都需要复杂的计算操作，如添加，乘法运算。因此，如果以数字方式实现，与目前已知的技术一样，接收机消耗了显着的高功率。与其数字计数器实现相比，我们的OFDM接收器组件被构建和设计为基于极低功率添加，乘法运算来处理离散时间模拟信号，因此实现了显着的功率降低。
