Abstract
Data is estimated of a plurality of received spread spectrum signals. The plurality of received communications are received in a shared spectrum. The received communications are sampled to produce a received vector. The received vector is processed to produce a plurality of segments. Each segment is processed separately to estimate data of the received communications.

A method for estimating data of a plurality of received spread spectrum communications, the plurality of received spread spectrum communications received in a shared spectrum, the method comprising:
- sampling the received communications to produce a received vector;
- processing the received vector to produce a plurality of segments representing continuous and overlapping portions of the received vector;
- and
- processing each segment separately to estimate data of the received communications.
A user equipment for estimating data of a plurality of received spread spectrum communications, the plurality of received spread spectrum communications received in a shared spectrum, the user equipment comprising:
- a sampling device configured to sample the received communications to produce a received vector;
- a segment-wise channel equalization data detection device configured to process the received vector to produce a plurality of segments representing continuous and overlapping portions of the received vector;
- and
- the segment-wise channel equalization data detection device configured to process each segment separately to estimate data of the received communications.
A base station for estimating data of a plurality of received spread spectrum communications, the plurality of received spread spectrum communications received in a shared spectrum, the base station comprising:
- a sampling device configured to sample the received communications to produce a received vector;
- a segment-wise channel equalization data detection device configured to process the received vector to produce a plurality of segments representing continuous and overlapping portions of the received vector;
- and
- the segment-wise channel equalization data detection device configured to process each segment separately to estimate data of the received communications.
A method for estimating data of a plurality of received spread spectrum communications, the plurality of received spread spectrum communications received in a shared spectrum, the method comprising:
- sampling the received communications to produce a received vector;
- processing the received vector to produce a plurality of segments representing continuous portions of the received vector such that each segment has at least one overlapping portion with another segment of the received vector;
- processing each segment separately to estimate data of the received communications including:
- equalizing each segment;
- discarding the overlapping portions of the segments after equalization;
- and
- despreading each segment.
A wireless communication apparatus configured to estimate data of a plurality of received spread spectrum communications, the plurality of received spread spectrum communications received in a shared spectrum, the apparatus equipment comprising:
- a sampling device configured to sample the received communications to produce a received vector;
- a processing component configured to process the received vector to produce a plurality of segments representing continuous portions of the received vector such that each segment has at least one overlapping portion with another segment of the received vector;
- and
- said processing component configured to process each segment separately to estimate data of the received communications by equalizing each segment, discarding the overlapping portions of the equalized segments and then despreading each segment.
