摘要： A wireless transceiver contains a receiver and a transmitter. The receiver is operable in single-input single-output (SISO) mode as well as multiple-input multiple-output (MIMO) mode, and contains a pair of in-phase and quadrature signal processing chains and a baseband processor. In SISO mode, each of the processing chains in the pair is connected to receive a same modulated signal as input, and generates respective baseband outputs. The baseband processor processes the baseband outputs to demodulate the modulated signal. In MIMO mode, the signal processing chains in the pair receive different modulated signals and generate corresponding down-converted signals. The baseband processor processes the down-converted signals to demodulate the respective modulated signals received by the receiver. Corresponding techniques to provide MIMO in addition to SISO capabilities are implemented in the transmitter also. MIMO capability is thereby achieved in the wireless transceiver with minimal additional implementation area.

摘要： A novel and useful apparatus for and method of closed loop IQ calibration for use in a transmitter. The IQ calibration mechanism functions to provide calibration of IQ imbalance in the presence of real world RF impairments. An iterative process is used to update the gain and phase mismatch values whereby the metrics are calculated in a differential manner without the need for calculation absolute imbalance values. At each iteration, updating the gain and phase mismatch estimate requires only the direction of the correction to be determined. The direction of the correction is calculated using only the differences between output power measurements. The updated gain and phase mismatch estimates are used to update an IQ correction matrix. This process is repeated until a desired stopping criterion is reached. Gear shifting is used to ensure quick convergence of the algorithm while providing the ability to achieve any desired level of accuracy.

摘要： A novel and useful apparatus for and method of distributed coexistence for mitigating interference in a single chip radio and/or a multi-radio (i.e. multi-transceiver) communications device. The invention enables coexistence ‘friendly’ radio IPs having frequency agility in that they are capable of shifting their clock frequencies thereby avoiding frequency bands of potential victim radios. Frequency agility on the aggressor radio side (rather than by mitigating the effect of interference on the victim radio side) prevents harmonics from the aggressor's clock scheme from falling in the operating frequency band of the victim radio, and in turn causing degradation to its performance. Each aggressor radio, based on information received from other radios, configures the root clock frequency of its RX and/or TX chain clock generation circuits.

摘要： A novel and useful apparatus for and method of local oscillator (LO) generation with non-integer multiplication ratio between the local oscillator and RF frequencies. The LO generation schemes presented are operative to generate I and Q square waves at a designated frequency while avoiding the well known issue of harmonic pulling. The input signal is fed to a synthesizer timed to a rational multiplier of the RF frequency L/N fRF. The clock signal generated is divided by a factor Q to form 2Q phases of the clock at a frequency of L(N*Q) fRF, wherein each phase undergoes division by L. The phase signals are input to a pulse generator which outputs a plurality of pulses. The pulses are input to a selector which selects which signal to output at any point in time. By controlling the selector, the output clock is generated as a TDM based signal. Any spurs are removed by an optional filter.

摘要： A novel robust communications scheme whereby a repetition code at the transmitter and an associated cumulative decoder at the receiver are used to increase the reliability of transmission in a communications system. The robust communications scheme of the present invention is effective to increase the reliability of transmission by repetitively transmitting each data segment a number of times in accordance with a repetition code and subsequently collecting the received energy at the receiver over an accordingly longer period of time. Accumulating the received energy over a longer period of time at the receiver, yields a marked improvement in the signal to noise ratio (SNR) of the receiver.

摘要： A novel and useful range extension and in-band noise mitigation mechanism that uses conventional CRC error detection codes to correct single and multiple bit errors in packets received over a communications link. The CRC error correction mechanism of the invention is particularly suitable for use with communication protocols with weak error correction capabilities. The mechanism uses the linearity property of the CRC calculation to detect the existence of errors in the received packet. The entire received packet is searched for single bit errors and are corrected in a single cycle. If no single bit errors are found, the mechanism then searches for multiple bit errors. Packet retransmissions are used to detect and mark the location of multiple bit errors. Multiple bit errors are corrected by trying a plurality of hypotheses of single bit error corrections. Each hypotheses pattern is investigated to find matching CRC patterns for correction using the single bit, single cycle CRC error correction method.
