摘要： A wireless communication system is provided that includes a base station receiving a plurality of input signals that are selectively provided to a plurality of precoders. The precoders perform precoding operations on the input signals and output a first signal. The base station includes an algorithm that minimizes total transmit power per antenna under signal to interference and noise ratio (SINR) target constraints or maximizes the SINR under a sum of power constraint so as to determine power allocation and obtain efficient precoders. A number of mobile receiver units receive the first signal and performs their respective operations to extrapolate the linear estimate of the input signals.

摘要： A TD-SCDMA receiver is provided that includes a joint detection (JD) block receiving a first input signal from a channel estimation block for signal detection. A short channel detection (SCD) block receives the first input signal and detecting the presence/absence of an AGWN-like channel based on the first input signal from the channel estimation block. The SCD block switches the JD block between 1× and 2× oversampling rates by sending to the JD block a second input signal.

摘要： A communication system is provided that includes a composite transfer module that receives an input signal and performs one or more selective operations defined by a first transfer function on the input signal. The composite transfer module outputs a first signal. A joint detection module receives the first signal and performs joint detection on the first signal. The joint detection module utilizes channel estimation information of the first transfer function so as to allow the joint detection module to perform joint detection with an oversampling rate of 2× or higher.
