Multicarrier receivers and methods for carrier frequency offset correction and channel estimation for receipt of simultaneous transmissions over a multi-user uplink are generally described herein. Other embodiments may be described and claimed.

Multi-user MIMO receiver and method for decoding simultaneous uplink transmissions from mobile stations

A user may wear the radio frequency human interface device on a body portion and move the body portion over any even and un-even surface that is not touch sensitive to provide inputs. The radio frequency human interface device may sense, encode, and provide the radio frequency signals to a computing system. The computing system may be provisioned with a radio frequency reader that may receive the radio frequency signal and decode the radio frequency signal before responding to the input. Also, a plurality of users may use radio frequency human interface devices to provide inputs to the computing system concurrently.

Human interface device (HID)

A wireless communication device that includes more than two antennas considers only two of those antennas for use in receiving any particular wireless packet. During reception of an initial portion of a wireless packet, a quality metric may be measured for each of the two antennas being considered. One of the two antennas may then be selected to receive a payload portion of the wireless packet based on the measured metrics. In at least one embodiment, a different pair of antennas is considered for each successive received packet.

Method and apparatus for achieving multiple antenna diversity with two antenna per packet diversity in a wireless network

Embodiments of System and Method for compensating for time-of-arrival differences between uplink packets in a Wireless Network are generally described herein. Other embodiments may be described and claimed.

Multicarrier receiver and method for time-delay compensation in a multi-user uplink

Each of a plurality of multicarrier wireless communication devices generate a carrier frequency offset (CFO) estimate from a downlink polling frame () and apply the CFO estimate to signals prior to transmission to a receiving station over a multi-user uplink.

Wireless communication device and method for reducing carrier frequency offsets over a simultaneous multi-user uplink in a multicarrier communication network

Method and embodiments in a multipath wireless communication system employing a wireless frame having alternating cyclic prefixes to reduce inter-symbol interference (ISI) are presented herein.

Wireless frame having alternating cyclic prefixes

Various embodiments of methods and apparatus to remove or reduce phase noise in a baseband signal at a receiver are generally described herein. Other embodiments may be described and claimed.

Multicarrier receiver and method with phase noise reduced signal

Multicarrier receiver and method for carrier frequency offset correction and channel estimation for receipt of simultaneous transmissions over a multi-user uplink

A decoder may include a constellation mapper arranged to receive a symbol and to determine two constellation points that are proximate the received symbol. An index mapper may determine a constellation index corresponding to the received symbol based on the received symbol and the two constellation points that are proximate the received symbol. A coset selector may receive successive constellation indices from the index mapper and may determine a number of nearest cosets to the successive constellation indices.

Decoding upstream V.92-encoded signals

A transmitter may transmit using OFDM-MIMO or OFDM-SDMA depending on channel characteristics.

Multiantenna communications apparatus, methods, and system

A method and apparatus to perform sample rate conversion using multiple Multiply-Accumulate (MAC) units are described.
