Abstract: A method and an apparatus for de-mapping symbols in a Multi-Input Multi-Output (MIMO) system are provided. In the present invention, an estimated channel effect and a plurality of received data symbols are used to estimate a plurality of transmitted data symbols. A plurality of constellation points around an estimated value are selected as the detected values of the transmitted data symbol after the estimated value of one of the transmitted data symbols is calculated. Then, the detected values are used to calculate the detected values of remaining transmitted data symbols separately so as to obtain a plurality of detected value sets. Finally, a best one among the detected value sets is chosen as a result of de-mapping the received symbols. Therefore, only a few detected value sets are calculated and a better detected result is obtained, which possesses low complexity and high performance.

Abstract: A power assisted vehicle includes an auxiliary propelling device disposed to the frame body. The auxiliary propelling device has an auxiliary wheel and at least one transmission portion disposed in the auxiliary wheel. When two friction wheels of the transmission portion fasten to two sides of a friction ring of the auxiliary wheel, and the two power sources is in reverse to drive the two friction wheels for rotating, a wheel rim and a tire are further driven to produce rotations. The power assisted vehicle is therefore capable of self-propelled going forward without any external force. A processing device is further disposed in the power assisted vehicle. The auxiliary propelling device is then activated when the power assisted vehicle is at a specific speed. The energy consumption for the power sources is then reduced and the service life is extended. The transmission force distribution generated from the power sources is further adjustable. The usage of the power assisted vehicle is more efficient.
